I'd like to put in an update to this thread, for anyone interested.
The backup server had been running Debian Etch. The version of amanda on
Etch was giving the errors described in this thread.
I upgraded the server to Debian Lenny. The problems still occured with the
version in Lenny.
Then I noticed that the version of amanda in Lenny dates from 2007. It
gives its version as:
1:2.5.2p1-4
When I look at the amanda.org download page and compare version numbers I
see this:
2.5.2p1 June 6 2007
Right, so the LATEST most up-to-date version of Debian uses a 3 year old
version of amanda. Fantastic, thanks Debian for keeping things so 'stable'.
I downloaded the actual latest stable version of amanda (2.6.1p2 from
November 2009), compiled it and tested it.
No bug.
Thanks, Debian package maintainer. Not.
Backup software is mission critical. Failing to track the upstream to this
extent is simply unforgivable. I'm revising my opinion of Debian.

Right - it was the failure I expected to see, not Steve's bug.
I'm not able to replicate Steve bug, many fix have been committed since
2.5.0p2.
Good point. By my back-of-the-envelope calculations, we've fixed
something like 500 bugs in the 4 years since 2.5.0 was released. Of
course, we *introduced* some of of those bugs in those 4 years, too :)
Steve: if you don't see something obvious that I missed in my
replication effort, can you give this a try with a 2.6.1p2 server?
I'm not able to make this test yet, perhaps later in the week.
However, I've discovered that the amcheck problem may not actually
reflect a genuine problem that affects backup.
The other day, the cronjob amcheck reported these errors -- so for one
thing its clearly intermittent.
But the thing is that the backup job that ran that very night completed
with no problems at all.

sorting office and expecting what is written on it to be private and secret
is not realistic. Please hold no higher expectation of email.
If you need to send confidential information in an email you need to use
encryption. PGP is Pretty good for this.
