I've been chasing this issue for a two weeks now. After an amount of time running varing between 3-5 days it seems, unraid will freeze and do one of two things. Either I get an nginx error trying to access the GUI or nothing responds at all. Recently it has been completely unresponsive. I cant even SSH into the machine. The hardware is a Dell T420 that has been my machine for about 3 years now without issue.
To try and dig in, I set the syslog to write to flash. Below is the most recent log. Looking at when my docker container for Unifi died, it appears to have gone unresponsive around 10:20-10:25am. I cant seem to find any evidence that would point to the issue and I'm at a loss. Unraid is on 6.12.4 and has been for a while now. Should I attempt an upgrade up? Any help is greatly appreciated!
