Ive just woken up to a unclean shutdown, i''ve consistently had these over the past year sometimes i can go 2/3 months with no issues and recently i've had two in this week. The fixes i've tried to help this is to disable xmp, allow a longer shutdown period roughly 7 minutes, kill any ssh/bash terminal sessions as i have been guilty of leaving them open before. I setup a syslog server on my pfsense which also doesn't point to any clues it just catches unraid rebooting. The unclean shutdown times are not consistent and are very sporadic i've noticed i've attached my diagnostics, if anyone has the time to have a look id really appreciate any help.

Server rebooting by itself is almost always a hardware problem, RAM and PSU are good places to start, if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.

Sorry i forgot to mention that id actually changed my ram as i thought this would be the issue, i did a memtest and a live memory test to rule this out, the psu is roughly 6 months old i do have a psu tester so ill give that a test when im back from work thanks

Note that memtest is only definitive if it finds errors, if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.

So I’ve just gotten home and I’ve tested the psu with a power supply tester and it failed on the PG so I’m going to assume this is the issue I will replace it and once it’s replaced I’ll run memtest too. Sucks because this power supply is only 7/8 months old too :(

I am having the same issue, and struggling to find the cause. Did your PSU replacement solve your issue?

Sorry for the late reply, i didn't actually have a hardware issue. My problem was Macvlan networking so i switched all my containers over to Ipvlan instead and i've been stable for over 2 months now, im pretty sure it was down to my unifi container causing random shutdowns as i found unifi doesn't handle multiple unique mac addresses well and can cause kernel panics if you encounter anything that sounds similar or use unifi, this might be the issue for you too.
