<li>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!</li>
<li>The top IPs before, during, and after this latest alert tonight were:</li>
<li>Switch CGSpace (linode18) to use OpenJDK instead of Oracle JDK</li>
<li>I manually installed OpenJDK, then removed Oracle JDK, then re-ran the <ahref="http://github.com/ilri/rmg-ansible-public">Ansible playbook</a> to update all configuration files, etc</li>
<li>Then I ran all system updates and restarted the server</li>
</ul>
<h2id="2018-12-02">2018-12-02</h2>
<ul>
<li>I noticed that there is another issue with PDF thumbnails on CGSpace, and I see there was another <ahref="https://usn.ubuntu.com/3831-1/">Ghostscript vulnerability last week</a></li>
</ul>

<li>Phil Thornton got an ORCID identifier so we need to add it to the list on CGSpace and tag his existing items</li>
<li>I created a GitHub issue to track this <ahref="https://github.com/ilri/DSpace/issues/389">#389</a>, because I’m super busy in Nairobi right now</li>
</ul>

<li>New <ahref="https://jdbc.postgresql.org/documentation/changelog.html#version_42.2.5">PostgreSQL JDBC driver version 42.2.5</a></li>
<li>I’ll update the DSpace role in our <ahref="https://github.com/ilri/rmg-ansible-public">Ansible infrastructure playbooks</a> and run the updated playbooks on CGSpace and DSpace Test</li>
<li>Also, I’ll re-run the <code>postgresql</code> 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</li>
<li>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:</li>

[Tue Jul 31 00:00:41 2018] oom_reaper: reaped process 1394 (java), now anon-rss:0kB, file-rss:0kB, shmem-rss:0kB
</code></pre><ul>
<li>Judging from the time of the crash it was probably related to the Discovery indexing that starts at midnight</li>
<li>From the DSpace log I see that eventually Solr stopped responding, so I guess the <code>java</code> process that was OOM killed above was Tomcat’s</li>
<li>I’m not sure why Tomcat didn’t crash with an OutOfMemoryError…</li>
<li>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</li>
<li>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</li>
<li>I ran all system updates on DSpace Test and rebooted it</li>
</ul>

<li>Test the <ahref="https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=560">DSpace 5.8 module upgrades from Atmire</a> (<ahref="https://github.com/ilri/DSpace/pull/378">#378</a>)
<ul>
<li>There seems to be a problem with the CUA and L&R versions in <code>pom.xml</code> because they are using SNAPSHOT and it doesn’t build</li>
</ul>
</li>
<li>I added the new CCAFS Phase II Project Tag <code>PII-FP1_PACCA2</code> and merged it into the <code>5_x-prod</code> branch (<ahref="https://github.com/ilri/DSpace/pull/379">#379</a>)</li>
<li>I proofed and tested the ILRI author corrections that Peter sent back to me this week:</li>
<li>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 <ahref="/cgspace-notes/2018-03/">March, 2018</a></li>
<li>Then I reduced the JVM heap size from 6144 back to 5120m</li>
<li>Also, I switched it to use OpenJDK instead of Oracle Java, as well as re-worked the <ahref="https://github.com/ilri/rmg-ansible-public">Ansible infrastructure scripts</a> to support hosts choosing which distribution they want to use</li>
</ul>
