freebsd-4.11-p3
bacula-1.36
onstream ADR50 SCSI External tape drive
well I just dont know what all this means so I am asking for some guidance. I
was backing up to an onstream ADR50 tape drive with bacula. The process since
errored and the daemon is stopped. I dont know why these Infinite interrupt
loop messages are ending up every minute in the /var/log/messages file.
clues please?
