truenas.local had an unscheduled system reboot

[Alex762]

Good day everyone. I've been running a very simple storage server with TrueNas for more than a year, and a few minutes ago I noticed that the system randomly rebooted. How do I know the exact cause of it? It's the first time that happened, I've tried checking the logs by using "more /var/log/messages" command in the shell but I couldn't find anything suspicious... The system is good, the dashboard doesn't report any issue and I can access it like I always did. The PSU is working nice, I just can't figure out what happened.

Overheating?
