August 31, 20187 yr Sometime around 3:40 AM last night, my server rebooted itself and ended up with a "stale configuration" and unclean shutdown. It's just starting a parity check. No disks are flagged as bad. Not sure what to make of this. Diags attacked. tower-diagnostics-20180831-1203.zip
August 31, 20187 yr Community Expert If the server unexpectedly reboots itself and there was no power cut then it almost certainly indicates that there must be an underlying hardware fault. Most likely problems would either be overheating (causing a thermal related shutdown) or power supply. The 3:40 is around the time mover normally runs which could well result in close to maximum load on the system. Edited August 31, 20187 yr by itimpi

September 1, 20187 yr Author Parity check no errors. Memtest one pass no errors. I am letting it run another pass to be sure.
September 6, 20187 yr Author Server hung last night sometime (did not reboot itself this time). Totally unresponsive this morning. Only a flashing cursor on the monitor. No access via the network, shares not visible and of course Plex not found. Had to hard reset the box to restart it. Looking at cache pool it didn't complete the Mover process. tower-diagnostics-20180906-0850.zip
