Hi Rodney,
The crashinfo file I sent was from the first crash. After It happened I went
to our NOC, rebooted the router and upgraded to 12.2.28SB6.
I re-applied the policy-map's again and got the second set of messages which I
sent to you in the smaller file. (none of which are in the crashinfo)
Unfortunately I don't have a crashinfo file from the second crash (I am not
sure why it was not saved).
Sorry I don't have proper output to debug from the second crash :>(.
Thanks to all fro the help, especially Rodney!
cheers
