Server was unresponsive for 40 minutes - can someone please help me review the logs to find the source?

[volcs0]

Around 9:30am CT this morning, my server became unresponsive - I could not get to the GUI nor could I SSH in. Over the next hour, I could intermittently SSH in but could not do anything - the system was pretty frozen. 

 

A little after 10:10 CT, everything started working again. I resisted the temptation to restart during the freeze up, because I wanted to see (1) if it came back, and (2) if I could isolate the source of the problem.

 

 

 

Diagnostics are attached.

 

Thanks.

The main issue I see was an OOM error:

 

Out of memory: Killed process 32593 (jellyfin)

 

That container was using a lot of RAM, so check the config or limit its RAM usage.
