Thank you for all your responses.
With all your help we have narrowed it down to a software bug and a customer
running a port scan. We were running Version 12.1(3a)T2 IOS and one of our
customers decided to run a port scan (We called them and asked what was he
doing). Someone told us to look for '%RCMD-4-RSHPORTATTEMPT:', we did and
found it just a few seconds before the router rebooted. He referenced that
attempt with the IOS a determined it was Cisco bug CSCds07326. We have
since upgraded our routers to the current IOS. Again thanks for all your
help.
Shawn.

I've heard that sort of problem rumored on the list recently; you may like
to have a look through the archives (on marc.theaimsgroup.com).
CSCdv06207 is not triggered by the operator, rather it's triggered by timing
of flow expiry in the router for the NBAR and ACL processes.
