Hi,

Can u pls take a " sh proc cpu sorted " output in ur router when you face this problem and also look at " sh proc cpu history " wheter the CPU had a hit before and how much is the hit.

This would help us to find wheter your router is having a problem or any other switches in the network is having the problem.

Also if possible , pls provide the router config and other details to look into the problem.

Plz. find attached Configuraton file with sh proc cpu 3 snaps on 15 minutes interval. as after every 15 minutes server broadcaste result to all hosts.at that time router shows heavy latency & timed out
