August 11, 20232 yr I have commented on other posts because my server seems to crash when Plex or Jellyfin are scanning files or running scheduled maintenance. It also seems to crash while trying to install Windows on a VM. There was nothing in the logs which points to a hardware issue but I've swapped almost everything out. I recently reduced my RAM speed to 2666 based on a suggestions from another post and now it's crashing more frequently. I managed to capture the screen as the server crashed just now and caught the following error. WARNING: CPU: 9 PID: 0 at arch/x86/kernel/fpu/core.c:424 kernel_fpu_begin_mask+0x30/0xcc And then the server crashed again while trying to download the syslog. I'm currently trying to diagnose the issue but can't find results here or on the wider internet regarding the message. Has the RAM speed change made things worse? Or merely exposed the RAM as the potential hardware issue? I ran memtest a few days ago and all was clear. Has anyone encountered this before? sakaar-diagnostics-20230811-2237.zip
August 14, 20232 yr Author Solution It looks like I had one bad RAM stick that has subsequently failed. Possibly due to overheating.
