[Mimedefang] MIMEDefang embedded perl stability issues

I'm on Redhat Linux 9 for the OS, latest kernel, etc. (through RHN update).
MIMEDefang version is 2.43, Spamassassin 2.63, and ClamAV 0.72. This problem
was fairly consistent when using the embedded perl interpreter, the MD
multiplexor would crash at almost the exact same time every morning (around
4-5am).  I don't encounter the problem when I'm not using embedded perl.

What OS are you on?  I don't observe this.

That's normal under Linux.  It uses memory aggressively to do file system
caching.
