yes

already did that. You can find it here. Last crash was today in the morning. Must have happened between 3 and 6. The backup scheduled for 6 has not been executed. I' restarted the machine at around 9:30... What component do you suspect? I've already exchanged mainboard, usb-drive and ram... CPU shows no problems with constant prime95 loads syslog-Gartenstr.log

Unfortunately, I have to unmark your solution. The crashes are back. Sometimes after a couple of hours, sometimes after a couple of minutes… I have now exchanged the RAM, but that also didn’t help. Any other ideas?

Thank you so much for your assistance! I’ve deactivated c-states in the bios completely and didn’t have any issues since then. It’s now running fine for 3 days. I really hope that this was the issue. I’ll mark your answer as the solution for now! The only thing that confuses me, is that’s the system was running stable for a couple of years and the crashes started without any changes in the c-state settings… Are there any changes to Unraid in the latest version that might have caused this? Thanks again for your help!!

Hi @all, I've been running an unraid server for a couple of years now without any issues, but since last week it crashes randomly. All containers, VM and GUI are frozen and I don't even get any ping responses. I cannot reproduce the error. Sometimes it's running fine for a day, sometimes not even 10 minutes. so far I've tried the following without success: setup log to a different server: no entries before or at the crashes run memtest86+: no errors run prime95 for about 1-2 hrs: so errors/crash updated unraid from 7.2.2 to 7.2.3 connect unraid to different ports/with different cables to switch exchanged the mainboard to a new one: no change replaced power supply with brand new one exchanged the usb stick and recreate unraid from usb-backup setup unraid from scratch and recreated containers, vms, plugins etc. from backup Nothing has helped so far… I’ve attached the diagnostics file. Any help or idea is much appreciated gartenstr-diagnostics-20260121-1457.zip
