Greetings,  my unraid server becomes unresponsive apparently randomly after a few weeks of uptime.  When it happens, no webui, ping or console display, though the pc is still running.  Reboot brings it back until next time.  6.12.10, diagnostic with syslog attached.  Thanks!

Could be unrelated, but still needs fixing, syslog shows flash drive problems:

Try using a different USB port, ideally USB 2.0, if errors persist, replace the flash drive.
