I hope this is helpful. Normally, the server becomes unresponsive. This time, I could access the UI, but Plex could not be accessed and Radarr's container would not start and displayed an "Execution Error". I shut down the server, pulled the USB drive and grabbed the syslog. I then turned the server back on and grabbed the Diagnostics. If that's not helpful, I can try again next time it crashes.
I do see a lot of errors in the Syslog:
Sep 6 05:34:35 Tower kernel: loop: Write error at byte offset 844185600, length 4096.
Sep 6 05:34:35 Tower kernel: I/O error, dev loop2, sector 1648800 op 0x1:(WRITE) flags 0x100000 phys_seg 1 prio class 2
Sep 6 05:34:35 Tower kernel: BTRFS error (device loop2: state EA): bdev /dev/loop2 errs: wr 4414, rd 0, flush 0, corrupt 2, gen 0
Then there's this, which is a relatively new development:
Thanks again.
