Whenever you see this behaviour you should run the offending message 
through MailScanner in debug mode and see what happens.

Most likely - you'll see a Perl error or a segfault which causes the 
child to crash and the batch to be reprocessed.

A recent version of MailScanner addressed an issue in HTML::Parser which 
was causing a Perl segfault on certain messages which contain excessive 
nesting.
