I've been having a reoccurring issue with my system for about 2 weeks now, and I had originally diagnosed it to be faulty memory but I have a new unbuffered ECC set that's passed 10 runs of memtest86+ and I'm at my wits end. Aside from the memory, the rest of the hardware is less than 2 years old. I have tried rolling the OS version back to an older one and it does not resolve the issue, but I can't find anything in the syslog that could point me in the right direction and have no idea where to start digging past that. There's nothing I can find that indicates a pattern, either.

 

I've attached the diagnostic report made after the last crash.

Assuming the syslog-previous cover crashes, there's nothing relevant logged, this usually points to 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.

If find it hard to believe the issue could be my hardware, as it's not nearly old enough to be failing. The one part in my system that could have been old enough would have been my memory, but now I have replaced it with tested good memory modules. The CPU is running at stock, the PSU is rated well and I'm using it with an UPS as well.

Assuming faulty hardware is not the root cause, what else could be causing complete shutdowns with no logging? From the research I've been doing, I'm leaning towards either my system is having temp spikes and shutting itself down, or the possibility that my flash drive is dying. Would I be able to test the flash drive in any capacity for failure?

Any hardware can fail at any time, even new one.

If the server shutdowns, vs. crashing or hanging, first suspects would be CPU temp or bad PSU, could also be board related.

I re-applied thermal paste and the issue wasn't reoccuring any more afterwards. Any chance there will be OS native temp monitoring? The fact that a plugin is required but troubleshooting steps involve disabling plugins seems very counterintuitive for temp-related issues like mine was.
