I've been running amanda for several months with
backups to disk
(amanda version 2.4.3).  Recently I've had backups
failing and can't
figure out what the problem may be.  

Some details:
 - Clients and backup server are Linux (RedHat 8)
 - backup disk has plenty of free space (80 GB drive
with only 35% in
use)

Below is an example report from one of the failed
dumps.  Nothing has
recently changed that "should" affect backups.  I
haven't found
anything to help point me in the right direction and
would appreciate
any points.

Thanks,
Chris
