April 7, 20242 yr Hi, I've been struggling lately with my unRAID server. It used to work fine, but a month ago it started rebooting randomly. Sometimes the server is up for 10 hours straight, sometime only for 10 minutes. I have no clue what's going on, neither have I found something specific that triggers a reboot. I only started to get "Unclean Shutdown Detected" message a week ago. I decided I will not leave the server on until I have addressed this issue. Things I've tried: - Updating from 6.12.7 to .8 to .9 and finally to .10. - Replacing the PSU for a new one (Corsair RM750e). - Reseating all the cables in the servers. - Plugging the power cable to directly to the wall instead of my UPS. - Running the server without docker and VM services on. - Monitoring temperatures and they are all fine. I'd greatly appreciate any guidance on this problem. Please find attached my diagnostics.zip cygnus-diagnostics-20240407-1811.zip Edited April 8, 20242 yr by Aerysv
April 8, 20242 yr Community Expert Server rebooting on its own, versus crashing or hanging, is almost always a hardware problem.

April 8, 20242 yr Community Expert Basically yes, since you have more than one RAM stick, you can try using just one, if the same try a different one, that will basically rule out the RAM.

So I did this and the server still crashes after trying two different sticks (one at a time). As I have already changed the PSU, I will try next a different board. I hope that fixes it
April 22, 20242 yr Author I still haven't solved the issue. I've changed the PSU, the motherboard and all sata cables, but the server keeps having unclean reboots.
April 22, 20242 yr I had a lot of issues like this, my advice might not be the best, but downgrading to 6.11.5 solved all my issues.
May 2, 20242 yr Author Solution After replacing every part in the server, but the CPU, the culprit turned out to be the USB drive. I replaced it, and the crashes stopped right away.
