<li><p>DSpace Test had crashed at some point yesterday morning and I see the following in <code>dmesg</code>:</p>
<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></li>
<li><p>Judging from the time of the crash it was probably related to the Discovery indexing that starts at midnight</p></li>
<li><p>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</p></li>
<li><p>I&rsquo;m not sure why Tomcat didn&rsquo;t crash with an OutOfMemoryError&hellip;</p></li>
<li><p>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</p></li>
<li><p>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</p></li>
<li><p>I ran all system updates on DSpace Test and rebooted it</p></li>
</ul>
