Router dumps core

[Tom Samplonius <tom@haven.uniserve.com>]

  I've been trying to get Zmailer installed on a production system 
previously running Sendmail.  I set up a test system which seemed to work 
fine, but after running for a few minutes on the production system, the 
router process dies with signal 11.

  I'm running it on a vanilla FreeBSD 1.1.5.1 system that's been very 
reliable otherwise.
