Hello Unraid team and fellow raiders? I hope you could spare some time to help out with my issue.

Over the past few weeks, my Unraid setup has become unresponsive multiple times. Docker services and WebUI does not respond.

Graceful shutdown is possible in the most recent incident. I have attached the diagnostics and syslog-previous files.

Additional note: Beszel monitoring shows the possible time it died, with metrics stopping around 26 Dec, 11:40 PM GMT +8.

Thank you!

There's an OOM event logged, so the first thing to do would be to fix that; memory exhaustion can end up crashing the server. HA VM was the one killed, but it does' mean it was the culprit, just the best candidate.

1. Only ~34 MB free RAM remained

2. Kernel determined all remaining memory was unreclaimable

3. Page cache was not the issue — memory was tied up in anonymous pages

You may need to limit the RAM for some containers, for example, or get a little more RAM, you can also just test running without some

Thanks for the advice! This is very helpful.

I will aim to download add more RAM. Meanwhile, I will shutdown not frequently used docker containers, and monitor the memory usage closer. I'll update as I get more details.
