This has happened two days in a row. I'm unsure the reason but things will freeze up. Yesterday this happened while I was working with a minecraft server in a docker container today it happened while working in a VM on some more demanding processes. I had something similar a few weeks back I think top showed something related to a process with `arc` in the name. I attached system diagnostics and the logs from my syslog.

Unfortunately there's nothing relevant logged, this usually points to a hardware issue, one thing you can try is to boot the server in safe mode with all docker containers/VMs disabled, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.

I appreciate the quick response, I did realize the syslog server was writing to a share so it's possible that went down when things froze up I updated it to store a copy on flash if it happens again i'll try to figure out what happened and I will try the safe mode, is there any other tools to check hardware for these potential issues?

Memtest is worth running, if you didn't yet, but it's only definitive if it finds errors.

The solution, at least as of the last two weeks was just to upgrade to the updated version on unraid, I had held off due to high use on my server but once I updated things haven't been crashing. Still not really sure how this all started, but it is resolved now.
