Unraid Keeps Crashing After Just a Couple Minutes of Uptime - PLEASE HELP!

[Gazeley]

This evening I noticed none of my docker services were working and I tried to go to the Unraid dashboard but it wasn't connectable. I had no choice but to hold the power button down on the server to force a shutdown, and turn it on again.

 

This brings Unraid back, and everything seems ok immediately after mounting the array, but after a couple minutes I inexplicably lose connection to everything again. I don't see any error messages or anything on the server CLI. Just the standard "SERVERNAME Login:" (SSH doesn't work either at this point, I'm seeing this on the monitor plugged into the server).

 

I did have enough time to get in there and grab the syslog which I've attached. I've been scrolling through it but I don't see anything obviously wrong.

 

Any help would be really appreciated, my whole family relies on the services hosted on this thing! Please let me know what other info I can provide to better troubleshoot.

Could not spot an obvious cause in that syslog.

 

Have you tried booting in Safe Mode?   This would identify if a plugin is causing your issue.

Does the system stay up if the array is not started?

Yeah the system seems to stay up just fine when the array isn't started. I also ran the Memtest for 30 min or so and didn't see any errors.

 

Now I have the array started with all the Dockers stopped, and I've been starting them one at a time with a few minutes in between to see if one in particular is crashing everything.

 

Is it possible for an individual Docker to crash the entire OS like this? I was running scrapers in the Stash docker at the time of the crashes. (Something I've done many times before without issue). If I get all my Dockers running and they stay stable for a few hours then I'll try running the scene scraper in Stash again to see if it triggers another crash.

It is unfortunately.   Plex has been a frequent culprit in the past but if it can crash the server then others could as well.   If the system stays up without the docker containers started then it definitely suggests one of them is the culprit.

So far it's been staying up. I'll try to narrow down exactly which Docker it is. Is there some sort of Docker syslog that I can look at after a crash to see what's going wrong and report to the developer? Normally I'd just use the logs pop-up on the Docker tab, but that's not much good in this situation since everything goes down when the issue occurs.

Not that I know of.  You can try reporting the issue in the support thread for the container.

I do have a very similar issue. Did a mem test, no issues. Run the USB stick trough fsck, seems fine too. 
 

What I experience is the Unraid Dashboard becoming unreachable, the docker containers still are up though. The device itself gets super hot and only a physical shutdown is possible for me. 
 

Checking Syslogs does not reveal anything to me. So I also suspect, one of the Dockers somehow is causing this. But being in the same question: How to find out which one it might be, when the system is not reachable for me. 
 

I checked for monitoring options and came across netdata. Will set it up, and hope seeing something after the next random unresponsiveness. 
 

Makes sense? Or you maybe have great better ideas regarding the monitoring in those moments?
