<li>New <a href="https://jdbc.postgresql.org/documentation/changelog.html#version_42.2.5">PostgreSQL JDBC driver version 42.2.5</a></li>
<li>I&rsquo;ll update the DSpace role in our <a href="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&rsquo;ll re-run the <code>postgresql</code> tasks because the custom PostgreSQL variables are dynamic according to the system&rsquo;s RAM, and we never re-ran them after migrating to larger Linodes last month</li>
<li>I&rsquo;m testing the new DSpace 5.8 branch in my Ubuntu 18.04 environment and I&rsquo;m getting those autowire errors in Tomcat 8.5.30 again:</li>

<ul>
<li>DSpace Test had crashed at some point yesterday morning and I see the following in <code>dmesg</code>:</li>
</ul>
<pre><code>[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
</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&rsquo;s</li>
<li>I&rsquo;m not sure why Tomcat didn&rsquo;t crash with an OutOfMemoryError&hellip;</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&rsquo;ll eventually need to upgrade to a larger one because we&rsquo;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>

<li>I want to upgrade DSpace Test to DSpace 5.8 so I took a backup of its current database just in case:</li>
</ul>
<pre><code>$ pg_dump -b -v -o --format=custom -U dspace -f dspace-2018-07-01.backup dspace
</code></pre><ul>
<li>During the <code>mvn package</code> stage on the 5.8 branch I kept getting issues with java running out of memory:</li>
</ul>
<pre><code>There is insufficient memory for the Java Runtime Environment to continue.

<ul>
<li>Test the <a href="https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=560">DSpace 5.8 module upgrades from Atmire</a> (<a href="https://github.com/ilri/DSpace/pull/378">#378</a>)
<ul>
<li>There seems to be a problem with the CUA and L&amp;R versions in <code>pom.xml</code> because they are using SNAPSHOT and it doesn&rsquo;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 (<a href="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>
</ul>
<pre><code>$ ./fix-metadata-values.py -i /tmp/2018-05-30-Correct-660-authors.csv -db dspace -u dspace -p 'fuuu' -f dc.contributor.author -t correct -m 3 -n
</code></pre><ul>
<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 <a href="/cgspace-notes/2018-03/">March, 2018</a></li>
<li>Time to index ~70,000 items on CGSpace:</li>

<pre><code>$ time schedtool -D -e ionice -c2 -n7 nice -n19 [dspace]/bin/dspace index-discovery -b

<li>I cleared the Solr statistics core on DSpace Test by issuing two commands directly to the Solr admin interface:
<ul>
<li>http://localhost:3000/solr/statistics/update?stream.body=%3Cdelete%3E%3Cquery%3E*:*%3C/query%3E%3C/delete%3E</li>
<li>http://localhost:3000/solr/statistics/update?stream.body=%3Ccommit/%3E</li>
</ul>
</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 <a href="https://github.com/ilri/rmg-ansible-public">Ansible infrastructure scripts</a> to support hosts choosing which distribution they want to use</li>

<li>Uptime Robot noticed that CGSpace went down and up a few times last night, for a few minutes each time</li>
<li>I didn&rsquo;t get any load alerts from Linode and the REST and XMLUI logs don&rsquo;t show anything out of the ordinary</li>
<li>The nginx logs show HTTP 200s until <code>02/Jan/2018:11:27:17 +0000</code> when Uptime Robot got an HTTP 500</li>
<li>In dspace.log around that time I see many errors like &ldquo;Client closed the connection before file download was complete&rdquo;</li>
<li>And just before that I see this:</li>
</ul>
<pre><code>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].
</code></pre><ul>
<li>Ah hah! So the pool was actually empty!</li>
<li>I need to increase that, let&rsquo;s try to bump it up from 50 to 75</li>
<li>After that one client got an HTTP 499 but then the rest were HTTP 200, so I don&rsquo;t know what the hell Uptime Robot saw</li>
<li>I notice this error quite a few times in dspace.log:</li>
