Proxmox shutdown last night, again.

It appears you have no scheduled jobs that should cause your problem. (I will assume you aren't using ZFS - even though you haven't directly informed us of this).

I'd look in the HA logs (Settings, System, Logs & right-hand side drop-down HOST) for this period of time & see what it shows. Also check the main HA core & supervisor logs & general logbook, you may find some activity there.

Even if you had (with setup) an API call from HA to shutdown the node host, this should show up in the PVE logs.

As another test - shutdown the HA VM next week before that 7/8am period, leaving the node up, & see what happens.

Forgot to mention in the stress-ng you should also test the network category. I've had enough mini pc's that play up that way.
Have a look at this wiki on the stress-ng usages/options.

I have a similar problem,

If this is also a NUC (which one?) ...

however I don't think my box is shutting down due to temp. The interesting thing is that it always shutdown exactly on Sunday morning, without fail. I've looked at the logs for couple weeks now. It's always just after pam_unix, as if somethin in those cron jobs are triggering a shutdown.

what's worse, the BIOS setting for S0 state don't restart it afterwards.

Despite what it looks like, I would try kernel param intel_idle.max_cstate=1 for a while, if not helpful, then 0 (to disable the driver).

In the last 3 lines before reboot, My shutdowns happen at exact minute and second. same 3 lines. Im finding this on multiple messages in this forum. I still haven't found a solution.

I used to run a intel nuc d34010wyk that was experiencing this issue. Then, after some time the SSD died, and I switched to a newer beelink, and still this issue.

One night i noticed that my UPS (Eaton 700) somehow wasn't charging and end up shutting down. I switched to another UPS and afterwards no more mysterious shutdown. It wasn't any setting nor any VM, just a faulty UPS.

just a faulty UPS.

That is really interesting, since AFAIR you always had that shutdown at 17 minutes past the hour on Sunday morning. Some increase in power usage / voltage change at that hour? Would be interesting to analyze on your system. What other devices are connected to that same UPS etc.?

My NAS is connected to it, also a bunch of other stuff like appleTV, router and stuff.
but non actually have any scheduled task that would spke power around that time... i checked there's nothing on my NAS that does that.
