I think this problem is a fluke and may never happen again, but I wanted to
document it anyway and see if anyone else had ideas.

I noticed this because TMDA wrote a zero-length file to the pending queue,
which inspired tmda-pending to complain when it hit it.  My daily cleanup
does something like this:

tmda-pending -O 21d -b -T | awk '{print $1}' | xargs tmda-pending -b -S

The blank file produced this at the first tmda-pending:

can't determine recipient address, skipping1088589374.2504.msg

Then xargs complained about a mismatched single quote.

I've tried to track down how that happened, and it's been pretty
confusing.  Whatever it is, it's not consistent because the message was
delivered on the second try, 20 minutes later.  Here's what Postfix logged:

Jun 30 04:56:14 longshot postfix/local[2487]: 94C94FE13F: to=<[EMAIL PROTECTED]>, 
relay=local, delay=34, status=deferred (temporary failure. Command output: LibClamAV 
Error: Wrote 0 instead of 512 (/tmp/clamav-ebf156e6a983b161/viruses.db). LibClamAV 
Error: cli_cvdload(): Can't unpack CVD file. ERROR: CVD extraction failure. See 
/home/kyle/.tmda/logs/debug-log for traceback )

TMDA's debug log has only a truncated line:

Uncaught Python 2.3.3 Excep

I think this is related to the same problem because the debug log was last
modified at the time of this error.

My poor computer is frequently overloaded.  Anything can happen when
software gets resource-starved, but I'd expect something to say "timeout"
in that case.

I think there's something wrong with clamAV too, but I wouldn't expect that
to hurt TMDA.  When it finds a virus, maildrop does 'tmda-filter -I X'
where X is a file that contains only 'to * hold'.  What can go wrong?

Maybe claimAV's complaints, falling on deaf ears, bled into TMDA somehow?

As I said, I think it's just a one-time problem, and I'm not worried about
it happening a lot.  Thanks for reading.
