My TrueNAS 25.04.1 keeps rebooting after a while. The logs only show systemd shutting down normally. Here are the logs. Does anyone know why?

My disks have warnings, but that shouldn’t cause a reboot, right?

Please post logs and such as Preformtted Text </> on toolbar or Ctrl+e. It’s easier to read.
Please post a detailed hardware listing, OS version. You can expand ‘Details’ under my post to get an idea of what I’m asking for.

We can only go off what you post to the forums, so please be detailed in what was happening with your system and any steps you have tried.

Without knowing anything else. I would suggest doing a CPU and memory stress tests with a Live Linux CD. Guessing hardware issues.
