Hang problem when building message batch

I'm having trouble with MailScanner 'hanging'.  The master process says
"waiting for children" and the child processes say "waiting for
messages".  If I run in debug mode using "MailScanner --debug" I get the
following output:

------------ 
[root at hcfw1 MailScanner]# MailScanner --debug


In Debugging mode, not forking...
Trying to setlogsock(unix)
Building a message batch to scan...

------------
At this point it 'hangs' and never comes back with a prompt.

I am running version 4.79.11 on a Cent-OS 5.4 system using sendmail as
the MTA.
