Ive been having crashing every few weeks recently. I'm on unraid 6.12.6. My docker containers are on ipvlan. Not sure when it crashed but I rebooted on Aug 9 7:41.

Unfortunately there's nothing relevant logged, this can be 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.

That sounds like a nightmare lol. Thanks I'll look into it.

when it happens my server is still physically running I just can't access unraid or anything. is there any common hardware failures I should look out for?

Could be RAM, board, CPU, PSU for example, but could also be a container or plugin.

I had another crash. Im guessing its the same deal. Its seems like its around the same time for whatever reason too.

Still nothing relevant logged I'm afraid.

I just changed a bunch of BIOS settings that if anything should help.

 

• PSU Idle power control to typical
• I disabled global C states
• turned off xmp
• turned off secure boot
• disabled onboard audio

and I'm running a memtest.

 

Not that I know anything but so far all the crashes have been overnight and for whatever reason the power button isn't functional while its crashed I need to pull the plug. That makes me wonder if it was related to the sleep settings that I disabled.

I had another crash today after all the changes. Its a shot in the dark and I did some reading and apparently people have issues with organizr being on /mnt/user/appdata/organizrv2 instead of /mnt/cache/appdata. If that doesn't fix it i'll run it in safemode and see what happens. I also had read that people have had issues with leaving the webui open all the time which I have been doing with unraid and organizr on 2 PCs. So I'll stop that and see what happens.

 

I'm just posting all this so if I ever solve this It'll hopefully help somebody in the future.

I’ve narrowed it down to Plex. I’ve even created a new container and it still crashes. It seems to be during scheduled tasks. There’s more than a few people with this issue online. I’ll have to narrow it down. 

Yep, there have been many other reports of Plex crashing servers.

Its been a pain in the ass but i've figured it out. No crash in over 3 weeks. The changes I made were i change the path to /mnt/cache/appdata/binhex-plexpass/ from the default that was /mnt/user/appdata/binhex-plexpass/ . I'm not sure if there will be any unintended consequences to this change but it worked for me.

 

The other thing I did was I added --no-healthcheck to the extra parameters in the docker container. Hopefully this helps people with the same issue in the future.
