<li>This morning Tomcat crashed due to an OOM kill:</li>
</ul>
<pre tabindex="0"><code>Sep 06 00:00:24 server systemd[1]: tomcat9.service: A process of this unit has been killed by the OOM killer.
Sep 06 00:00:25 server systemd[1]: tomcat9.service: Main process exited, code=killed, status=9/KILL
Sep 06 00:00:25 server systemd[1]: tomcat9.service: Failed with result &#39;oom-kill&#39;.
</code></pre><ul>
<li>According to the system journal, it was a Node.js dspace-angular process that tried to allocate memory and failed, thus invoking the OOM killer</li>
<li>Currently I see high memory usage in those processes:</li>

<li>I bet if I look in the logs I&rsquo;d find some kind of heavy traffic on the frontend, causing high caching for Angular SSR</li>

<ul>
<li>Analyzing memory use in our DSpace hosts, which have 32GB of memory
<ul>
<li>Effective cache of PostgreSQL is estimated at 11GB, which seems way high since the database is only 2GB</li>
<li>Realistically this should be how we adjust, with PostgreSQL using ~8GB (or less) and each dspace-angular process pinned at 2GB&hellip;</li>
</ul>
</li>

<p>Total - Solr - Tomcat Postgres - Nginx - Angular
31366 − (1024×4.4) − 7168 − (8×1024) − 512 - (4x2048) = 2796.4 left&hellip;</p>

<ul>
<li>I put some of these changes in on DSpace Test and will monitor this week</li>
