Diagnostics attached. Thanks in advance for your help.

Try this and post that log after a crash, if you haven't yet also a good idea to run memtest.

Not sure if the syslog worked, but I've attached it. MemTest looks good - although I couldn't run it from the Unraid boot - I had to go to the website and create a new USB with just that on it to run MemTest. Could that be part of the problem?

Memtest only works if you boot in legacy mode, it won't in UEFI mode, nothing on the syslog that I can see, one thing you can try it to boot the server in safe mode with all docker/VMs disable, 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.

OK thanks for that. I'm now getting an MCE warning from fix common problems. Any chance you see something in the attached, or is there a specific MCE area?

 

(The machine is headless and I haven't moved it back to a monitor yet so unless there's an option to boot to safe mode from the GUI, I haven't been able to do that yet - I stupidly put it away after running memtest)

IIRC they show up in the syslog with mcelog installed, but in any case it points to a hardware problem.

OK, I'm trying to sift through the syslog now. I did waste a lot of space with csrf_token errors from having browser sessions open across a reboot. This is the only thing I've found that looks like it might be on point and I can't make heads or tails of it:

Start by running memtest.

Hello randomjohn at the Moment i have the same Problem in this Post 

 

the same Problem was caused by the Plex Container an his Maintenance run maybe you can disable the Docker temporaly and test if there are further crashes.
I did this today too

I ran both Memtest86+ 5.01 (thanks for your heads up to boot in legacy mode) and MemTest 86 v0.4. They each ran for at least four passes and about 20 additional hours and returned no errors.

 

I've been running error-free in Safe Mode for ~24 hours now. Will be rather annoyed (but relieved) if it's the same problem @Wingold refers to - at least I'll know, but a significant part of the hardware purchase and Unraid installation was to up the horsepower for Plex streaming.

 

Any of this look interesting or relevant? Still trying to figure out what's going on with the ntp server.

They point to a hardware problem, but don't identify the component.

That's what I was afraid of. Any recommendations for good diagnostics? Weird that it would start after two months. Usually it's right away or after a long time. I did add and move fans, which significantly dropped internal temps but maybe that was too late.

 

I've attached the most-recent diagnostics, but I don't really know what I'm looking for and nothing leapt out at me.

 

Thanks for all your help.

Anything can go bad at any time, if the diags don't point to the culprit basically you'd need to start swapping components around to find it.

I guess we can consider this one closed but not solved.

 

• While it ran properly before a BIOS update came out recently for my motherboard, I installed that, then I upgraded to Unraid test build (and now RC-1) from 6.8 stable.
• I significantly increased the overall system cooling to where the NVME drive is now about 10C cooler at idle in reaction to some temp warnings I was getting. Mobo and CPU are about 5C cooler (~29C at idle)
• Finally, I spent a lot of time tracking down NTP errors and switched out some of the default google servers for the NTP pool for my region.

 

I really hope I'm not jinxing anything, but I was at 4 days of error-free uptime when I posted this. Hopefully something in here helps the next poor soul.
