- 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
       4432 200

- In the last two weeks there have been 47,000 downloads of this same exact PDF by these three IP addresses
- Apply country and region corrections and deletions on DSpace Test and CGSpace:

    $ ./fix-metadata-values.py -i /tmp/2019-02-21-fix-9-countries.csv -db dspace -u dspace -p 'fuuu' -f cg.coverage.country -m 228 -t ACTION -d
    $ ./fix-metadata-values.py -i /tmp/2019-02-21-fix-4-regions.csv -db dspace -u dspace -p 'fuuu' -f cg.coverage.region -m 231 -t action -d
    $ ./delete-metadata-values.py -i /tmp/2019-02-21-delete-2-countries.csv -db dspace -u dspace -p 'fuuu' -m 228 -f cg.coverage.country -d

- 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!
- The top IPs before, during, and after this latest alert tonight were:

    # zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "01/Feb/2019:(17|18|19|20|21)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

        405 207.46.13.173
        405 207.46.13.75
       1117 66.249.66.219
       1121 35.237.175.180
       1546 5.9.6.51
       2474 45.5.186.2
       5490 85.25.237.71

- `85.25.237.71` is the “Linguee Bot” that I first saw last month
- The Solr statistics the past few months have been very high and I was wondering if the web server logs also showed an increase
- There were just over 3 million accesses in the nginx logs last month:

    # time zcat --force /var/log/nginx/* | grep -cE "[0-9]{1,2}/Jan/2019"
    3018243

- Linode alerted that CGSpace (linode18) had a higher outbound traffic rate than normal early this morning
- I don’t see anything interesting in the web server logs around that time though:

    # zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "02/Jan/2019:0(1|2|3)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

- Switch CGSpace (linode18) to use OpenJDK instead of Oracle JDK
- I manually installed OpenJDK, then removed Oracle JDK, then re-ran the Ansible playbook to update all configuration files, etc
- Then I ran all system updates and restarted the server

## 2018-12-02

- I noticed that there is another issue with PDF thumbnails on CGSpace, and I see there was another Ghostscript vulnerability last week

- Phil Thornton got an ORCID identifier so we need to add it to the list on CGSpace and tag his existing items
- I created a GitHub issue to track this #389, because I’m super busy in Nairobi right now

- 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
