Just about every night I have at least one (sometimes more) containers with a failed backup; The status of task cryptically just says "32052: Oct 30 07:31:48 ERROR: Backup of VM 32052 failed - CT is locked (backup)"

The lock isnt clears and remains so until manually cleared via pct unlock. Isn't the lock present FOR the backup? please help troubleshoot.
