Public bug reported:
When there is more backup output data to store than fits on the (virtual) tape,
Amanda hangs.
The expected behavior is to terminate the backup, and email (when launched from
crond) the backup report.
Relevant part of the "ps aux" output:

The above has been happening for a few days, requiring manual intervention
after each backup run.
If all backup output data fits on the provided tape, everything works fine.

of Amanda where data didn't fit on the tape (host and dle names
