UnRAID machine randomly shut down overnight - trying to diagnose what happened from the syslogs

[Magic815]

Hi all - 

 

So I'm running UnRAID v6.12.10, and last night (Sept 12th, at ~11:00pm local time to me) I got notifications on my phone that all of the services I run on my UnRAID machine went offline - indicating my server crashed and/or shut down. I was already asleep at the time, so I noticed this in the morning when I woke up. Heading to the machine, I confirmed that it was completely shut down.

 

Clicking the power button this morning booted the UnRAID machine back up just fine. There is no ongoing parity check, which indicates to me that whatever shutdown event occurred last night was not considered to be an unclean shutdown.

 

When inspecting the syslogs, I believe this to be the section of time where something went wrong to cause the shutdown:

Does anyone have any insight into what might have occurred? This is the first time I've seen this type of behavior on this server. Full diagnostics are attached.

Make sure you don't have a plugin or script running a shutdown command, it could also be a bad power button or a cat/child in the house pressing it.

None of my scripts or plugins have changed recently, none contain a shutdown command, and wouldn't some indication of said script/plugin initiating a shutdown show up in the syslogs/diagnostic data? Children were asleep hours before this shutdown event. We do have a cat, but the server is inside a metal rack/shelf that would make it tough for them to reach the power button - so I'd consider that very unlikely. Does anything in the syslog or diagnostics indicate that it was a physical press of the case's power button?

Not really, but something or someone, initiated a server shutdown.
