[Mimedefang] Filter timed out

[Ashley M. Kirchner]

    Mail is flowing.  That's the good news.  Even under high load, everything
is flowing nicely.  However, occasionally I will get one of them stuck and I
see this in my syslog:

        mimedefang[23863]: Error from multiplexor: ERR Filter timed out
        sendmail[23842]: g3RMN5w6023842: Milter: data, reject=451 4.7.1
                         Please try again later


    How can I find out what's causing this to happen?  That "stuck" message
never gets delivered.
