Hey all,

I have been having issues with my server going unresponsive...

I am unable to SSH in or access the GUI - but the unit is pingable. If I hit the power button, I hear the drives shut down and the box shuts down cleanly. And I am able to bring it back up without issue. I have the syslog mirrored to the flash drive to capture it. I am attaching my logs for review.

I'm afraid there's not much logged:

The only thing out of the ordinary is the MSI RGB disconnecting in the middle of the night, I would think that's not a reason to crash the server, but post a new syslog after the next crash for comparison.

I actually have the last few saved to my flash drive. Ill upload them. Could this be a NIC issue? I wouldnt think so as I can still ping it. I dont think its locked up either as I hit the power button one time and it cleanly shuts down.

Assuming that syslog-previous also covers a crash, the same issue is not logged, nor nothing else relevant that I can see.

Since the server still shuts down, it appears to be a software 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 doesn't crash like that, start turning on the other services one by one, including the individual docker containers.

Attaching the latest logs. I was home when it went offline (Watching a movie on Plex) - Sadly, disabling the docker/services would make the unit useless for us. We utilize the dockers for our Plex container.

Assuming the syslog-previous covers another event, I'm afraid there's still nothing relevant logged that I can see.

I think I found the culprit:

Looks like my DHCP is having issues. I put in a new firewall and confirmed I was able to connect right to it (Using the new DHCP lease) without rebooting the server. This was not an unraid issue but a firewall issue.

Closing this out!
