I've been dealing with an issue for a couple months where the system will crash/shutdown with little indication of a specific issue. I have the BIOS set to turn the system back on after a power loss so the system comes back up and I can see in the Unraid interface that it wants to do a parity check due to an unclean shutdown. The time between crashes is extremely variable. Sometimes the system will be fine for a month and other times barely 24 hours before a crash. I have the syslog set to mirror to a share so I have attached that as well as the diagnostics zip. The latest crash and restart was approximately an hour before posting this so what I have of the syslog from mirroring is limited to the past two days. Specs and things I have already done are below. I've have been running Unraid for a while now and have never seen an issue like this before so I am really at a loss. For next steps I was thinking replace the motherboard. Are there other steps that might be helpful before that though? Are there any specific things that cause Unraid to completely crash like this? I'd sincerely appreciate any help anyone has to offer as I am pretty distressed by this now.
