- 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

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:

- 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:

- 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

- 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

- 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.
