TNEF loop infinite loop problem?

[Bryan Guest]

Hi:

One of my mail blades running Mailscanner got stuck in some sort of loop 
this morning, dealing with a TNEF attachment/message.   The Inbound Queue 
shot up because MailScanner was accepted new messages but not processing any 
of them while it choked on this message.

I stopped mailscanner and pulled this message out of the queue and everthing 
recovered.

Has anyone seen this before, and is there some config change I need to make 
to prevent it?

Redhat ES 4
Mailscanner 4.56.8-1
tnef    1.4.3-1  (redhat native)

MailScanner.conf TNEF settings:
Expand TNEF = yes
Use TNEF Contents = replace
Deliver Unparsable TNEF = no
TNEF Expander = /usr/bin/tnef --maxsize=100000000
TNEF Timeout = 120

MailScanner log sample (repeats ad nauseum):
