MailScanner crashing

[Johnson, SE]

I've seen a few posts out there but no one with my exact issue...

Periodically I'm getting the message similar to this in my logs:

I didn't think much of it at first until I realized in the MailWatch
program that many of these messages were legitimate.  

I tried MailScanner --lint which came up clean
spamassassin --lint is clean as well

I then tried to reprocess one of the messages in the queue with:
MailScanner --debug --ID=[messageid] 
(while I was in the quarantine dir)

The program starts to process it I got

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

But it never seems to go past this... I let it sit for over an hour and
it never came back...

I then found a reference to debug-sa... I ran MailScanner --debug
--debug-sa and got:
15:54:34 Building a message batch to scan...
(long pause)
Then I get the final output with no issues being reported.

Does anyone know what I can do to find my issue?  
Thanks!
