So over the last couple of days I have had a couple of total freezes of Unraid. The server becomes completely unresponsive. Shares, webgui or SSH are not accessible. I haven't found a way to reproduce it but my guess is that it must be connected to some background activities (like parity check or mover) but I cannot confirm this as it does not happen all the time. And of course I cannot exclude hardware errors.
- The first time it was booted in default mode (no GUI) and the cursor kept blinking, but the keyboard was non-responsive. I had just replaced a HDD and it had begun the rebuild when it froze. When I got it up again it started over and completed successfully.
- The other time I was booted in GUI mode and the entire screen was just frozen (mouse+keyboard non-responsive). This must have happened during the night and I didn't use it for anything.
Both times I had to cut power to get it up again.
I have updated all plugins and dockers, I've also run a successful memtest. I have no idea what to look for in logs etc, but I have included the diagnostics as directed.
