November 18, 2025Nov 18 I've been having an issue recently on both 7.1.4 and 7.2.0 where my server would restart and then fail to boot.FYI, I'm running unraid on bare metal, a Supermico Motherboard and an HBA SAS Backplane. I've been running Unraid for 10 years on the same hardware and have had my share of issues, but never this one. I have not changed the hardware at all. This started happening after I had been on 7.1.4 for a long time. I even migrated Unraid to a new USB thinking there was an issue with the old one not being recognized. I honestly don't see a lot of info about this error. I found one post in the virtualization forum but I don't think that's the same issue. I have 8 HDDs for my array and 2 SSDs for my cache. Any help pointing me in the right direction would be appreciated.

I'm able to boot into Unraid on a fresh install. I was also able to boot into Unraid the first time after a fresh install + copying over my config folder. I was only unable to boot into Unraid after my server restarted a couple times.What would this tell me? What kind of config would cause an issue like this?

November 22, 2025Nov 22 Community Expert If that works, I would try restoring a few config files/folders at a time to try and find the culprit.

November 23, 2025Nov 23 Author @JorgeB I know this is technically unrelated to the posted issue, but one of the reasons I've been needing to boot is due to random server reboots. I'm able to get the system event log and this showed up:Would bad memory cause a reboot? Unraid has been rebooting within a minute or so of fully booting up from a clean install. However, the server does not reboot while in bios. Currently running memtest86 but no errors so far through 32%.

Too impatient to run more. I was able to boot into unraid with fresh-ish configs (all but plugins). Server is now rebooting quite often, 5 minutes or less. I pulled G1 and H1 RAM sticks just now since they are part of the same channel to see if that helps. Any chance this could be PSU related? I'm not getting any IPMI errors about it.
