That's strange. Can you strace/ktrace/truss some of the processes to
see what's going on?

and then use OS-level tracing tools.

You could have a script that checks if the pids in the MD and multiplexor
pid files are still running, I suppose. We have a monitoring script for
CanIt, but it won't work with generic MIMEDefang because our CanIt
init script is very different.

Those look like network problems. They are sendmail processes on
your end attempting to connect to remote hosts.
