You are getting a busy timeout, which means your filter is taking more
than 30 seconds to process the message.  Possible causes:

- A bug in the filter causing it to loop forever
- An overloaded system -- you have 8 running slaves, which is quite a lot.
- Something in your filter which is slow on large messages.  Old versions
  of SpamAssasssin behaved badly on large messages.

You can try increasing the busy timeout (-b 300) to five minutes.  If
that does not help, then it's probably a filter error.

Try using the "-k" option to mimedefang.  That will keep failed spool
directories around.  Then you can test your filter "live" by doing
this:

	cd /var/spool/MIMEDefang/mdefang-whatever
	rm -rf Work
	mimedefang.pl .

That will run the Perl filter on the actual spool directory.  See
how long it takes.
