Atmire merged some changes I had submitted to the COUNTER-Robots project
I updated our local spider user agents and then re-ran the list with my check-spider-hits.sh script on CGSpace:

$ ./ilri/check-spider-hits.sh -f /tmp/agents -p  
Purging 1989 hits from The Knowledge AI in statistics
Purging 1235 hits from MaCoCu in statistics
Purging 455 hits from WhatsApp in statistics

Total number of bot hits purged: 3679

I experimented with manually sharding the Solr statistics on DSpace Test
First I exported all the 2019 stats from CGSpace:

$ ./run.sh -s http://localhost:8081/solr/statistics -f 'time:2019-*' -a export -o statistics-2019.json -k uid
$ zstd statistics-2019.json

Export all affiliations on CGSpace and run them against the latest RoR data dump:

localhost/dspace63= > \COPY (SELECT DISTINCT text_value as "cg.contributor.affiliation", count(*) FROM metadatavalue WHERE dspace_object_id IN (SELECT uuid FROM item) AND metadata_field_id = 211 GROUP BY text_value ORDER BY count DESC) to /tmp/2021-10-01-affiliations.csv WITH CSV HEADER;
$ csvcut -c 1 /tmp/2021-10-01-affiliations.csv | sed 1d > /tmp/2021-10-01-affiliations.txt
$ ./ilri/ror-lookup.py -i /tmp/2021-10-01-affiliations.txt -r 2021-09-23-ror-data.json -o /tmp/2021-10-01-affili
ations-matching.csv
$ csvgrep -c matched -m true /tmp/2021-10-01-affiliations-matching.csv | sed 1d | wc -l 
1879
$ wc -l /tmp/2021-10-01-affiliations.txt 
7100 /tmp/2021-10-01-affiliations.txt

So we have 1879/7100 (26.46%) matching already

Troubleshooting the missing Altmetric scores on AReS
- Turns out that I didn’t actually fix them last month because the check for content.altmetric still exists, and I can’t access the DOIs using _h.source.DOI for some reason
- I can access all other kinds of item metadata using the Elasticsearch label, but not DOI!!!
- I will change DOI to tomato in the repository setup and start a re-harvest… I need to see if this is some kind of reserved word or something…
- Even as tomato I can’t access that field as _h.source.tomato in Angular, but it does work as a filter source… sigh
I’m having problems using the OpenRXV API
- The syntax Moayad showed me last month doesn’t seem to honor the search query properly…

Update Docker images on AReS server (linode20) and reboot the server:

# docker images | grep -v ^REPO | sed 's/ \+/:/g' | cut -d: -f1,2 | grep -v none | xargs -L1 docker pull

I decided to upgrade linode20 from Ubuntu 18.04 to 20.04

Export another list of ALL subjects on CGSpace, including AGROVOC and non-AGROVOC for Enrico:

localhost/dspace63= > \COPY (SELECT DISTINCT LOWER(text_value) AS subject, count(*) FROM metadatavalue WHERE dspace_object_id in (SELECT dspace_object_id FROM item) AND metadata_field_id IN (119, 120, 127, 122, 128, 125, 135, 203, 208, 210, 215, 123, 236, 242, 187) GROUP BY subject ORDER BY count DESC) to /tmp/2021-07-01-all-subjects.csv WITH CSV HEADER;
COPY 20994

IWMI notified me that AReS was down with an HTTP 502 error
- Looking at UptimeRobot I see it has been down for 33 hours, but I never got a notification
- I don’t see anything in the Elasticsearch container logs, or the systemd journal on the host, but I notice that the angular_nginx container isn’t running
- I simply started it and AReS was running again:

I looked at the top user agents and IPs in the Solr statistics for last month and I see these user agents:
- “RI/1.0”, 1337
- “Microsoft Office Word 2014”, 941
I will add the RI/1.0 pattern to our DSpace agents overload and purge them from Solr (we had previously seen this agent with 9,000 hits or so in 2020-09), but I think I will leave the Microsoft Word one… as that’s an actual user…

I wrote a script to query Sherpa’s API for our ISSNs: sherpa-issn-lookup.py
- I’m curious to see how the results compare with the results from Crossref yesterday
AReS Explorer was down since this morning, I didn’t see anything in the systemd journal
- I simply took everything down with docker-compose and then back up, and then it was OK
- Perhaps one of the containers crashed, I should have looked closer but I was in a hurry

Discuss some OpenRXV issues with Abdullah from CodeObia
- He’s trying to work on the DSpace 6+ metadata schema autoimport using the DSpace 6+ REST API
- Also, we found some issues building and running OpenRXV currently due to ecosystem shift in the Node.js dependencies

CGSpace CG Core v2 Migration

Sun, 21 Feb 2021 13:27:35 +0200

Changes to CGSpace metadata fields to align more with DC, QDC, and DCTERMS as well as CG Core v2. Implemented on 2021-02-21.

With reference to CG Core v2 draft standard by Marie-Angélique as well as DCMI DCTERMS.

Abenet said that CIP found more duplicate records in their export from AReS
- I re-opened the issue on OpenRXV where we had previously noticed this
- The shared link where the duplicates are is here: https://cgspace.cgiar.org/explorer/shared/heEOz3YBnXdK69bR2ra6
I had a call with CodeObia to discuss the work on OpenRXV
Check the results of the AReS harvesting from last night:

$ curl -s 'http://localhost:9200/openrxv-items-temp/_count?q=*&pretty'
{
  "count" : 100875,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0

Peter notified me that some filters on AReS were broken again
- It’s the same issue with the field names getting .keyword appended to the end that I already filed an issue on OpenRXV about last month
- I fixed the broken filters (careful to not edit any others, lest they break too!)
Fix an issue with start page number for the DSpace REST API and statistics API in OpenRXV
- The start page had been “1” in the UI, but in the backend they were doing some gymnastics to adjust to the zero-based offset/limit/page of the DSpace REST API and the statistics API
- I adjusted it to default to 0 and added a note to the admin screen
- I realized that this issue was actually causing the first page of 100 statistics to be missing…
- For example, this item has 51 views on CGSpace, but 0 on AReS

Atmire responded about the issue with duplicate data in our Solr statistics
- They noticed that some records in the statistics-2015 core haven’t been migrated with the AtomicStatisticsUpdateCLI tool yet and assumed that I haven’t migrated any of the records yet
- That’s strange, as I checked all ten cores and 2015 is the only one with some unmigrated documents, as according to the cua_version field
- I started processing those (about 411,000 records):

Continue with processing the statistics-2019 Solr core with the AtomicStatisticsUpdateCLI tool on DSpace Test
- So far we’ve spent at least fifty hours to process the statistics and statistics-2019 core… wow.

Add tests for the new /items POST handlers to the DSpace 6.x branch of my dspace-statistics-api
- It took a bit of extra work because I had to learn how to mock the responses for when Solr is not available
- Tag and release version 1.3.0 on GitHub: https://github.com/ilri/dspace-statistics-api/releases/tag/v1.3.0
Trying to test the changes Atmire sent last week but I had to re-create my local database from a recent CGSpace dump
- During the FlywayDB migration I got an error:

Replace Marissa van Epp for Rhys Bucknall in the CCAFS groups on CGSpace because Marissa no longer works at CCAFS
The AReS Explorer hasn’t updated its index since 2020-08-22 when I last forced it
- I restarted it again now and told Moayad that the automatic indexing isn’t working
Add Alliance of Bioversity International and CIAT to affiliations on CGSpace
Abenet told me that the general search text on AReS doesn’t get reset when you use the “Reset Filters” button
- I filed a bug on OpenRXV: https://github.com/ilri/OpenRXV/issues/39
I filed an issue on OpenRXV to make some minor edits to the admin UI: https://github.com/ilri/OpenRXV/issues/40

I spent a few days working on a Java-based curation task to tag items with ISO 3166-1 Alpha2 country codes based on their cg.coverage.country text values
- It looks up the names in ISO 3166-1 first, and then in our CGSpace countries mapping (which has five or so of Peter’s preferred “display” country names)
- It implements a “force” mode too that will clear existing country codes and re-tag everything
- It is class based so I can easily add support for other vocabularies, and the technique could even be used for organizations with mappings to ROR and Clarisa…

A few users noticed that CGSpace wasn’t loading items today, item pages seem blank
- I looked at the PostgreSQL locks but they don’t seem unusual
- I guess this is the same “blank item page” issue that we had a few times in 2019 that we never solved
- I restarted Tomcat and PostgreSQL and the issue was gone
Since I was restarting Tomcat anyways I decided to redeploy the latest changes from the 5_x-prod branch and I added a note about COVID-19 items to the CGSpace frontpage at Peter’s request

I tried to run the AtomicStatisticsUpdateCLI CUA migration script on DSpace Test (linode26) again and it is still going very slowly and has tons of errors like I noticed yesterday
- I sent Atmire the dspace.log from today and told them to log into the server to debug the process
In other news, I checked the statistics API on DSpace 6 and it’s working
I tried to build the OAI registry on the freshly migrated DSpace 6 on DSpace Test and I get an error:

Peter said that CTA is having problems submitting an item to CGSpace
- Looking at the PostgreSQL stats it seems to be the same issue that Tezira was having last week, as I see the number of connections in ‘idle in transaction’ and ‘waiting for lock’ state are increasing again
- I see that CGSpace (linode18) is still using PostgreSQL JDBC driver version 42.2.11, and there were some bugs related to transactions fixed in 42.2.12 (which I had updated in the Ansible playbooks, but not deployed yet)

Maria asked me to update Charles Staver’s ORCID iD in the submission template and on CGSpace, as his name was lower case before, and now he has corrected it
- I updated the fifty-eight existing items on CGSpace
Looking into the items Udana had asked about last week that were missing Altmetric donuts:
- The first is still missing its DOI, so I added it and tweeted its handle (after a few hours there was a donut with score 222)
- The second item now has a donut with score 2 since I tweeted its handle last week
- The third item now has a donut with score 1 since I tweeted it last week
On the same note, the one item Abenet pointed out last week now has a donut with score of 104 after I tweeted it last week

Update dspace-statistics-api for DSpace 6+ UUIDs
- Tag version 1.2.0 on GitHub
Test migrating legacy Solr statistics to UUIDs with the as-of-yet unreleased SolrUpgradePre6xStatistics.java
- You need to download this into the DSpace 6.x source and compile it

Continue working on porting CGSpace’s DSpace 5 code to DSpace 6.3 that I started yesterday
- Sign up for an account with MaxMind so I can get the GeoLite2-City.mmdb database
- I still need to wire up the API credentials and cron job into the Ansible infrastructure playbooks
- Fix some minor issues in the config and XMLUI themes, like removing Atmire stuff
- The code finally builds and runs with a fresh install

Open a ticket with Atmire to request a quote for the upgrade to DSpace 6
Last week Altmetric responded about the item that had a lower score than than its DOI
- The score is now linked to the DOI
- Another item that had the same problem in 2019 has now also linked to the score for its DOI
- Another item that had the same problem in 2019 has also been fixed

2020-01-07

Peter Ballantyne highlighted one more WLE item that is missing the Altmetric score that its DOI has
- The DOI has a score of 259, but the Handle has no score at all
- I tweeted the CGSpace repository link

Upgrade CGSpace (linode18) to Ubuntu 18.04:
- Check any packages that have residual configs and purge them:
- # dpkg -l | grep -E ‘^rc’ | awk ‘{print $2}’ | xargs dpkg -P
- Make sure all packages are up to date and the package manager is up to date, then reboot:

# apt update && apt full-upgrade
# apt-get autoremove && apt-get autoclean
# dpkg -C
# reboot

Peter noticed that there were 5.2 million hits on CGSpace in 2019-10 according to the Atmire usage statistics
- I looked in the nginx logs and see 4.6 million in the access logs, and 1.2 million in the API logs:

# zcat --force /var/log/nginx/*access.log.*.gz | grep -cE "[0-9]{1,2}/Oct/2019"
4671942
# zcat --force /var/log/nginx/{rest,oai,statistics}.log.*.gz | grep -cE "[0-9]{1,2}/Oct/2019"
1277694

So 4.6 million from XMLUI and another 1.2 million from API requests
Let’s see how many of the REST API requests were for bitstreams (because they are counted in Solr stats):

# zcat --force /var/log/nginx/rest.log.*.gz | grep -c -E "[0-9]{1,2}/Oct/2019"
1183456 
# zcat --force /var/log/nginx/rest.log.*.gz | grep -E "[0-9]{1,2}/Oct/2019" | grep -c -E "/rest/bitstreams"

2019-10-01 Udana from IWMI asked me for a CSV export of their community on CGSpace I exported it, but a quick run through the csv-metadata-quality tool shows that there are some low-hanging fruits we can fix before I send him the data I will limit the scope to the titles, regions, subregions, and river basins for now to manually fix some non-breaking spaces (U+00A0) there that would otherwise be removed by the csv-metadata-quality script’s “unneccesary Unicode” fix: $ csvcut -c 'id,dc.

Deploy ORCID identifier updates requested by Bioversity to CGSpace
Run system updates on CGSpace (linode18) and reboot it
- Before updating it I checked Solr and verified that all statistics cores were loaded properly…
- After rebooting, all statistics cores were loaded… wow, that’s lucky.

Last month Sisay asked why the following “most popular” statistics link for a range of months in 2018 works for the CIAT community on DSpace Test, but not on CGSpace:
- DSpace Test
- CGSpace
Abenet had another similar issue a few days ago when trying to find the stats for 2018 in the RTB community

Help CCAFS with regenerating some item thumbnails after they uploaded new PDFs to some items on CGSpace
A user on the dspace-tech mailing list offered some suggestions for troubleshooting the problem with the inability to delete certain items
- Apparently if the item is in the workflowitem table it is submitted to a workflow
- And if it is in the workspaceitem table it is in the pre-submitted state
The item seems to be in a pre-submitted state, so I tried to delete it from there:

dspace=# DELETE FROM workspaceitem WHERE item_id=74648;
DELETE 1

But after this I tried to delete the item from the XMLUI and it is still present…

Meeting with AgroKnow to discuss CGSpace, ILRI data, AReS, GARDIAN, etc
- They asked if we had plans to enable RDF support in CGSpace
There have been 4,400 more downloads of the CTA Spore publication from those strange Amazon IP addresses today
- I suspected that some might not be successful, because the stats show less, but today they were all HTTP 200!

# cat /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep 'Spore-192-EN-web.pdf' | grep -E '(18.196.196.108|18.195.78.144|18.195.218.6)' | awk '{print $9}' | sort | uniq -c | sort -n | tail -n 5

In the last two weeks there have been 47,000 downloads of this same exact PDF by these three IP addresses

I checked IITA’s 259 Feb 14 records from last month for duplicates using Atmire’s Duplicate Checker on a fresh snapshot of CGSpace on my local machine and everything looks good
I am now only waiting to hear from her about where the items should go, though I assume Journal Articles go to IITA Journal Articles collection, etc…
Looking at the other half of Udana’s WLE records from 2018-11
- I finished the ones for Restoring Degraded Landscapes (RDL), but these are for Variability, Risks and Competing Uses (VRC)
- I did the usual cleanups for whitespace, added regions where they made sense for certain countries, cleaned up the DOI link formats, added rights information based on the publications page for a few items
- Most worryingly, there are encoding errors in the abstracts for eleven items, for example:
- 68.15% � 9.45 instead of 68.15% ± 9.45
- 2003�2013 instead of 2003–2013
I think I will need to ask Udana to re-copy and paste the abstracts with more care using Google Docs

Linode has alerted a few times since last night that the CPU usage on CGSpace (linode18) was high despite me increasing the alert threshold last week from 250% to 275%—I might need to increase it again!

New PostgreSQL JDBC driver version 42.2.5
I’ll update the DSpace role in our Ansible infrastructure playbooks and run the updated playbooks on CGSpace and DSpace Test
Also, I’ll re-run the postgresql tasks because the custom PostgreSQL variables are dynamic according to the system’s RAM, and we never re-ran them after migrating to larger Linodes last month
I’m testing the new DSpace 5.8 branch in my Ubuntu 18.04 environment and I’m getting those autowire errors in Tomcat 8.5.30 again:

DSpace Test had crashed at some point yesterday morning and I see the following in dmesg:

[Tue Jul 31 00:00:41 2018] Out of memory: Kill process 1394 (java) score 668 or sacrifice child
[Tue Jul 31 00:00:41 2018] Killed process 1394 (java) total-vm:15601860kB, anon-rss:5355528kB, file-rss:0kB, shmem-rss:0kB
[Tue Jul 31 00:00:41 2018] oom_reaper: reaped process 1394 (java), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB

Judging from the time of the crash it was probably related to the Discovery indexing that starts at midnight
From the DSpace log I see that eventually Solr stopped responding, so I guess the java process that was OOM killed above was Tomcat’s
I’m not sure why Tomcat didn’t crash with an OutOfMemoryError…
Anyways, perhaps I should increase the JVM heap from 5120m to 6144m like we did a few months ago when we tried to run the whole CGSpace Solr core
The server only has 8GB of RAM so we’ll eventually need to upgrade to a larger one because we’ll start starving the OS, PostgreSQL, and command line batch processes
I ran all system updates on DSpace Test and rebooted it

I want to upgrade DSpace Test to DSpace 5.8 so I took a backup of its current database just in case:

$ pg_dump -b -v -o --format=custom -U dspace -f dspace-2018-07-01.backup dspace

During the mvn package stage on the 5.8 branch I kept getting issues with java running out of memory:

There is insufficient memory for the Java Runtime Environment to continue.

I added the new CCAFS Phase II Project Tag PII-FP1_PACCA2 and merged it into the 5_x-prod branch (#379)
I proofed and tested the ILRI author corrections that Peter sent back to me this week:

I think a sane proofing workflow in OpenRefine is to apply the custom text facets for check/delete/remove and illegal characters that I developed in March, 2018

- http://localhost:3000/solr/statistics/update?stream.body=%3Ccommit/%3E
Then I reduced the JVM heap size from 6144 back to 5120m
Also, I switched it to use OpenJDK instead of Oracle Java, as well as re-worked the Ansible infrastructure scripts to support hosts choosing which distribution they want to use

Uptime Robot noticed that CGSpace went down and up a few times last night, for a few minutes each time
I didn’t get any load alerts from Linode and the REST and XMLUI logs don’t show anything out of the ordinary
The nginx logs show HTTP 200s until 02/Jan/2018:11:27:17 +0000 when Uptime Robot got an HTTP 500
In dspace.log around that time I see many errors like “Client closed the connection before file download was complete”
And just before that I see this:

Caused by: org.apache.tomcat.jdbc.pool.PoolExhaustedException: [http-bio-127.0.0.1-8443-exec-980] Timeout: Pool empty. Unable to fetch a connection in 5 seconds, none available[size:50; busy:50; idle:0; lastwait:5000].

Ah hah! So the pool was actually empty!
I need to increase that, let’s try to bump it up from 50 to 75
After that one client got an HTTP 499 but then the rest were HTTP 200, so I don’t know what the hell Uptime Robot saw
I notice this error quite a few times in dspace.log:

2018-01-02 01:21:19,137 ERROR org.dspace.app.xmlui.aspect.discovery.SidebarFacetsTransformer @ Error while searching for sidebar facets

I looked in the Activity pane of the Admin Control Panel and it seems that Google, Baidu, Yahoo, and Bing are all crawling with massive numbers of bots concurrently (~100 total, mostly Baidu and Google)
The good thing is that, according to dspace.log.2017-08-01, they are all using the same Tomcat session
This means our Tomcat Crawler Session Valve is working
But many of the bots are browsing dynamic URLs like:
- /handle/10568/3353/discover
- /handle/10568/16510/browse
The robots.txt only blocks the top-level /discover and /browse URLs… we will need to find a way to forbid them from accessing these!
Relevant issue from DSpace Jira (semi resolved in DSpace 6.0): https://jira.duraspace.org/browse/DS-2962
It turns out that we’re already adding the X-Robots-Tag "none" HTTP header, but this only forbids the search engine from indexing the page, not crawling it!
Also, the bot has to successfully browse the page first so it can receive the HTTP header…
We might actually have to block these requests with HTTP 403 depending on the user agent
Abenet pointed out that the CGIAR Library Historical Archive collection I sent July 20th only had ~100 entries, instead of 2415
This was due to newline characters in the dc.description.abstract column, which caused OpenRefine to choke when exporting the CSV
I exported a new CSV from the collection on DSpace Test and then manually removed the characters in vim using g/^$/d
Then I cleaned up the author authorities and HTML characters in OpenRefine and sent the file back to Abenet

Interestingly, it seems DSpace 4.x’s thumbnails were sRGB, but forcing regeneration using DSpace 5.x’s ImageMagick plugin creates CMYK JPGs if the source PDF was CMYK (see 10568/51999):

Testing adding ORCIDs to a CSV file for a single item to see if the author orders get messed up
Need to test the following scenarios to see how author order is affected:
- ORCIDs only
- ORCIDs plus normal authors
I exported a random item’s metadata as CSV, deleted all columns except id and collection, and made a new coloum called ORCID:dc.contributor.author with the following random ORCIDs from the ORCID registry:

0000-0002-6115-0956||0000-0002-3812-8793||0000-0001-7462-405X

Discuss helping CCAFS with some batch tagging of ORCID IDs for their authors
Discuss how the migration of CGIAR’s Active Directory to a flat structure will break our LDAP groups in DSpace
We had been using DC=ILRI to determine whether a user was ILRI or not
It looks like we might be able to use OUs now, instead of DCs:

$ ldapsearch -x -H ldaps://svcgroot2.cgiarad.org:3269/ -b "dc=cgiarad,dc=org" -D "admigration1@cgiarad.org" -W "(sAMAccountName=admigration1)"

Add updated distribution license from Sisay (#259)
Play with upgrading Mirage 2 dependencies in bower.json because most are several versions of out date
Bootstrap is at 3.3.0 but upstream is at 3.3.7, and upgrading to anything beyond 3.3.1 breaks glyphicons and probably more
bower stuff is a dead end, waste of time, too many issues
Anything after Bootstrap 3.3.1 makes glyphicons disappear (HTTP 404 trying to access from incorrect path of fonts)
Start working on DSpace 5.1 → 5.5 port:

$ git checkout -b 55new 5_x-prod
$ git reset --hard ilri/5_x-prod
$ git rebase -i dspace-5.5

Add dc.description.sponsorship to Discovery sidebar facets and make investors clickable in item view (#232)
I think this query should find and replace all authors that have “,” at the end of their names:

dspacetest=# update metadatavalue set text_value = regexp_replace(text_value, '(^.+?),$', '\1') where metadata_field_id=3 and resource_type_id=2 and text_value ~ '^.+?,$';
UPDATE 95
dspacetest=# select text_value from  metadatavalue where metadata_field_id=3 and resource_type_id=2 and text_value ~ '^.+?,$';
 text_value
------------
(0 rows)

In this case the select query was showing 95 results before the update

Experimenting with IFPRI OAI (we want to harvest their publications)
After reading the ContentDM documentation I found IFPRI’s OAI endpoint: http://ebrary.ifpri.org/oai/oai.php
After reading the OAI documentation and testing with an OAI validator I found out how to get their publications
This is their publications set: http://ebrary.ifpri.org/oai/oai.php?verb=ListRecords&from=2016-01-01&set=p15738coll2&metadataPrefix=oai_dc
You can see the others by using the OAI ListSets verb: http://ebrary.ifpri.org/oai/oai.php?verb=ListSets
Working on second phase of metadata migration, looks like this will work for moving CPWF-specific data in dc.identifier.fund to cg.identifier.cpwfproject and then the rest to dc.description.sponsorship

Looking at log file use on CGSpace and notice that we need to work on our cron setup a bit
We are backing up all logs in the log folder, including useless stuff like solr, cocoon, handle-plugin, etc
After running DSpace for over five years I’ve never needed to look in any other log file than dspace.log, leave alone one from last year!
This will save us a few gigs of backup space we’re paying for on S3
Also, I noticed the checker log has some errors we should pay attention to:

Looking at issues with author authorities on CGSpace
For some reason we still have the index-lucene-update cron job active on CGSpace, but I’m pretty sure we don’t need it as of the latest few versions of Atmire’s Listings and Reports module
Reinstall my local (Mac OS X) DSpace stack with Tomcat 7, PostgreSQL 9.3, and Java JDK 1.7 to match environment on CGSpace server

Looking at some DAGRIS data for Abenet Yabowork
Lots of issues with spaces, newlines, etc causing the import to fail
I noticed we have a very interesting list of countries on CGSpace:

Not only are there 49,000 countries, we have some blanks (25)…
Also, lots of things like “COTE D`LVOIRE” and “COTE D IVOIRE”

Move ILRI collection 10568/12503 from 10568/27869 to 10568/27629 using the move_collections.sh script I wrote last year.
I realized it is only necessary to clear the Cocoon cache after moving collections—rather than reindexing—as no metadata has changed, and therefore no search or browse indexes need to be updated.
Update GitHub wiki for documentation of maintenance tasks.

CGSpace went down
Looks like DSpace exhausted its PostgreSQL connection pool
Last week I had increased the limit from 30 to 60, which seemed to help, but now there are many more idle connections:

$ psql -c 'SELECT * from pg_stat_activity;' | grep idle | grep -c cgspace
