March 10, 20251 yr I have a really frustrating issue that happened 3 times now. The most recent happened overnight when I started parity sync after replacing all drives I wanted to upgrade (had no parity drive for a couple of weeks). The Web UI and SSH were unreachable, the GUI over iGPU (slim command) was frozen (at parity 7.5% sync so it happened after a few hours). Even the num-lock wasn't working on the keyboard or the power button. I had to hold the power button to force a shutdown. The drives were still active so I assume parity and pre-clearing were still happening. What can cause Unraid to freeze like this but still continue parity sync and pre-clearing? I have recently upgraded motherboard/cpu/ram/psu though had no crashes for about a week after that while transferring data. Anyone have any idea where to start looking for the cause? Unraid version 7.0.1 Diagnostics don't appear to have anything from before latest boot. unraid-diagnostics-20250310-1054.zip Edited March 10, 20251 yr by dominicm
March 10, 20251 yr Author No crash so far but I found another issue that's potentially related. I figured I should create a new topic as the symptoms are very different: https://forums.unraid.net/topic/187971-parity-sync-progress-and-pausestop-stuck-when-pre-clearing-another-disk/
March 14, 20251 yr Author Had another crash, this time num lock worked and GUI was not frozen but unraid would not prompt for password after entering username. System froze after starting pre-clear on a second disk. After reset I was able to start pre-clearing all 6 disks with no freezing. I see segfaults in the log, is this the cause of my issues? Would appreciate advise how I should proceed at this point. Please see attached syslog. syslog-192.168.0.100.log

March 17, 20251 yr Author Just did 2 passes with no errors so I assume RAM not the issue. Is there a good way to test the CPU on Unraid?

Nothing reliable as far as I know, but since memtest is only definitive if it finds errors, if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.
March 18, 20251 yr Author The crashes are rare so hard to test. I hope the BIOS update ended up fixing it otherwise not sure what else to do. Oddly the crashed only happened when pre-clearing.
