I'm having a problem on our network with eigrp flapping on our routers, I've narrowed it down to one of our 6509's that's showing high cpu utization...in the log I get holding time expired events for EIGRP (the other routers get peer restarted)...I'm not sure if the high cpu is because of the eigrp flapping or the eigrp flapping is because of high cpu...I'm assuming the high cpu is causing it because all the neighbors flap, not just one router.
Here are some of the show outputs:
