April 25, 20188 yr Been running unraid for years on older hardware with no issues. About a year ago I got a newer (old) SuperMicro board with 16GB so I could run dockers. Periodically the system will reboot, which in turn causes a parity check. The interesting thing is the frequency of the reboots is considerably reduced if I have the Common Problems plugin running its diagnostics. Finally however, it rebooted while diagnostics were running - but I don't see anything in the logs which points me to the issue. Hopefully someone else will?

April 25, 20188 yr Community Expert I would be looking at hardware if you haven't already. Be checking things like power connections to the MB, That all the RAM modules are securely locked in their sockets. Even disconnect the connector that goes from the MB to 'Reboot' button on the case (One guy found that his cat was 'pushing' this button. Children have also been involved in these types of shenanigans.) Ran a memtst for a minimum of 24 hours. Make sure that the cooling fans are all running (and continue to run if you power them back for energy savings). Make sure that the air inlets are clean. That PCU heatsink fin assembly is clean. Make sure that the Capacitors on the MB are not swollen. Think about the history of that MB. Why was it available? And what do you know of its history?
