[Mimedefang] No Free Slaves

[Charles Mount]

I am running MimeDefang 2.32  on SUN 420s with 4 processors and 4GB on
Solaris8 with Sendmail-Switch.  I am primarily calling SpamAssassin,  Virus
checking is handled separately.
The lines below are from /var/log/syslog.   Hopefully, the first line has
enough config info.  Everything works well except I see these occasional
error messages.
Should I tweak the config a bit?
