<div dir="ltr">Hi Cliff,<div><br></div><div>I want to share a small collection of my thoughts that might be useful here.<br><div><br></div><div>Are your ASpace instances set to take advantage of the expanded memory?

Something like bulk updating top containers, entities, etc.? That could lead to situations where memory is quickly consumed and the OS either stalls, or unceremoniously kills off the app as an act of self-preservation. </div><div><br></div><div>I'd also check web server logs.

<p class="MsoNormal">Hi folks,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">TL;DR: Our production ArchivesSpace server is occasionally crashing with no warning/log info. I’d love to know if anyone else is experiencing this issue.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We’re running ArchivesSpace 3.4.0 on two virtual machine (VM) servers in parallel: one for Development (4 GB memory), one for Production (16 GB memory). Both servers are on Ubuntu 22.04.2.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Occasionally, the Production VM will freeze up completely, to the point where we can’t log in, and have to do a “hardware” reset through ESXi. Once we reset the server, login, and reboot the ASpace software, everything runs fine for a while
until it freezes up again.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We tried putting the Development VM through a bunch of stress testing to see if we could replicate the issue, but we haven’t been able to get it to freeze up.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Has anyone else experienced anything like this, where their underlying operating system/hardware is crashing beneath ArchivesSpace?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thanks!<u></u><u></u></p>
