Issue:

After 3 years of rock-solid performance with hardly any downtime, Unraid server suddenly crashes and reboots with LOTS of parity errors on a frequent basis (uptime is usually 5-10 minutes, rarely up for a few hours). I'm not much of a tinkerer (if it isn't broken, don't fix it), so I'm at a loss for what might have changed.

 

Attached diagnostic file and the live syslog from the latest crash (one of the few I could pull down before another crash). Would someone mind taking a look and let me know if anything jumps out at you?

 

I appreciate any insights or suggestions you could offer. Thank you!

Don't see anything relevant logged, could be a hardware issue, sync errors might just be a result of the unclean shutdowns, one thing you can try it to boot the server in safe mode with all docker/VMs disable, let it run as a basic NAS for a few days, if it still crashes it's likely a hardware problem, if it doesn't start turning on the other services one by one.
