[Mimedefang] Out Of Memory

[Mike Carlson]

I finally MIMEDefang up and running on my BSD box, but now
/var/log/maillog has the following error quite often:
Apr  5 14:14:56 hades mimedefang-multiplexor: Starting slave 1 (pid 277)
(2 running): Bringing slaves up to minSlaves (2)
Apr  5 14:14:59 hades mimedefang-multiplexor: Slave 7 stderr: Out of
memory! 
Apr  5 14:14:59 hades mimedefang-multiplexor: Reap: Idle slave 7 (pid
276) exited normally with status 1 (SLAVE DIED UNEXPECTEDLY)
Apr  5 14:14:59 hades mimedefang-multiplexor: Slave 7 resource usage:
req=0, scans=0, user=6.280, sys=0.737, nswap=0, majflt=0, minflt=16333,
maxrss=31656, bi=0, bo=0

What would be causing the error?
