The traceback, unfortunately, doesn't demangle the C++ subroutine names nor provide source line numbers, but the best that I can tell is that the heap has been corrupted, Bacula detects is, then does a Kaboom (self inflicted seg fault). Are you by any chance pointing the tapealert/smartmonctl at the tape drive device rather than at the scsi control device? If you are, I am not surprised, and you should remove it as two different programs cannot properly exist using the same tape device. If you are pointing it at the scsi control device, I would be interested to see what the normal output of the command gives back as there may be a possible buffer overrun though that really should not happen. In any case, I recommend that you remove the tape alert for a time and see if that eliminates the problem. > > This does not happen every day, but every once in awhile... it occurs at > the end of a set of concurrent backups to tape -- all incrementals, 7 in > total.

For a problem with tape alert, it is very unlikely that upgrading to 2.1.x will help. > > Thanks for any insights you can provide -- I'd be happy to report a bug > if it is needed. Until I see your response and think about it, I don't think this is worth a bug report, at least not just yet.
