Proxmox 4 Rebooted self?

[dragon2611]

Seems my Proxmox 4 machine rebooted itself sometime around 05:45 - 06:00 GMT, the thing is I can't see any obvious reason why it would have done so, there's nothing noteworthy in syslog/messages, the BMC didn't log anything either.

Any ideas?

Is there any other logs I should be checking for crash dumps.etc?

Maybe a hardware problem ? Overheating ?

I don't think it's overheating as there's nothing in the BMC/IPMI logs for any of the onboard temperature sensors to suggest a thermal event.

Hi, new to the forum today Actually we encountered a problem 4 times within two weeks now. After re-configuring our cluster, and updating it to 3.4-11/6502936f, has happened 4 times that one machine was shut down by the other via SNMP (so tells us our hardware manufacturer support) . Happened at random times, no idea what could be the reason yet. lets stay updated thanks Andre, uibmz

I had a similar problem with an Intel chassis last year rebooting Proxmox, after much trial and error it turned out that the power supply was getting a bit tired. Replaced it and all good.

Hi thanks for your reply.
Our logs say the reason for shutdown is an ACPI Event triggered from another Proxmox Server. Seems to be the right track still.
