Hello,

Since a few weeks, i'm having multiple stability problems in this Unraid server.

WebUI is crashing within 1 hour to 10 days.
Dockers seems to be always up (i can watch emby without problems)
Only solution is for me to hard reboot the server.

I check the ram, XPM is disabled.

I can't link the crash to anything specific.

I can't found anything suspicious in the syslog

I just tried to disable the c-state option in the bios, let's see.

So, if someone have i clue, i would gladly take some help :)

before anyone pointed that up, i just activated ssh to be able to restart nginx when it crashes again.

Make sure this has all been taken care of:

So i did everything in that post, it will crash randomly.

Here the last diagnostics file from yesterday

• C state is disable, it doesn't seems to be the problem

• I thought it could be the VM because i crashed 1 or 2 times while i was using it

• Yesterday, even with the VM down, the server crashed.

• When it crashes, i'm not able to SSH so, it seems like it's not only the webui. However, like before, most of my dockers are still up.

Thank you for you help

Enable the syslog server and post that after the next crash; also, disable mover logging not to spam it.

Here's the file. Sorry i was away for a few weeks.

Seems like we see the crash. Is that nginx ? I'm not able to SSH when it crashes so, it would be weird that it's only NGINX.

syslog-previous

Do those nginx messages correspond to the time the server crashed? Also, please try booting in safe mode and retest to rule out a plugin issue.

here's another crash.

yes the nginx crashing seems to be it.

crash 21-09-2025

Try safe mode.

I am having precisely the same problem, also where GUI goes down first, then some of the dockers slowly, in many days interval.

The same story somewhat, clean memtest, changed cache SSD (running appdata), changed USB, that is running straight from motherboard. It started randomly after some update in Q1 2025.
In the end I set it to daily reboot at night, that fixed it... to most extent. Aka had 2 times where it went belly up anyway within the 24hrs.

Since this thread is still active; please start a new one and post the diagnostics after you encounter the problem and before rebooting.

I will try. But when GUI goes down, you dont notice it for days sometimes, but the SSH connection also goes down. So you cannot reboot softly/access anything before rebooting.
I started syslog server, as the only option otherwise?

Yes, post that after the issue (in a new thread, please)
