During last night's backups, I got tons of errors in /var/log/messages,
enough to run /var out of space.  The following is a brief sample; there
are about 400 messages (5 lines each) per second.

Has anyone seen this?  It seems like a combination of a hardware error
and amanda being overly aggressive.
