Mail Not Routing, stuck in /var/spool/mqueue.in

[Desai, Jason]

Not sure if this will help or not, but I have noticed MailScanner on my
backup/test server hanging.  An strace of the process showed nothing.  But
ls -l /proc/<pid>/fd/ showed that it had some of the SpamAssassin bayes
database files opened.  This is running MailScanner version 4.22-5 and
SpamAssassin version 2.54.

The strange thing is that MailScanner had been hung for over a day!  I would
have thought that MailScanner would have timed out SpamAssassin by then.
Killing MailScanner and restarting would fix the problem for a while, then
it would happen again.  I know that some people who are having this problem
are not using SpamAssassin, but perhaps there is a problem in the time out
code for SpamAssassin or Virus Checking?

I'm not complaining.  My main MailScanner server is working, and I set
"use_bayes 0" on my backup, and that seemed to clear its problem.  The
backup is a 233 MHz with 128 Mb of ram, and has other functions besides
scanning email, so it is taxed when MailScanner scans email.

Anyways, maybe this helps - if not, just ignore.
