We are seeing the same problem on all of the 6400-nrp aggregation boxes we
have in the network. Here is the IOS bug ID - CSCec12495.. Actually by rate
limiting icmp on our network the problems have stopped/slowed down a lot.
Sorry for the delay.. Was out of the country for a while..

Hi Robert,
Thanks for the info. We are running dCEF...routers show about 4% CPU load
and the following memory:
BR02#sh mem
Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)
Processor 613AE340 247798976 106515996 141282980 140653360
134546752
Fast 6138E340 131080 37240 93840 93840 93788
Also, we are not blocking 92 byte ICMP due to the traceroute problems on
customers networks...
Thanks
