libmilter has a "feature" that I've complained bitterly about to Claus
Assman.  If pthread_create() fails too many times in a row, libmilter
calls exit(), and basically you're dead in the water.  I've observed
this on a very busy mail server.

I sent a patch to sendmail.org to fix this; no word yet if it's been
accepted.

My solution, like yours, was to have a script that runs once a minute
to verify that mimedefang and mimedefang-multiplexor are still running,
and restart if something goes wrong.  I don't watch the logfile, though;
I just "kill -0 `cat /var/spool/MIMEDefang/mimedefang.pid`" (similarly
for the multiplexor) and restart everything if either kill fails.
