HSRP flap for no reason on Nexus 7K

kthned
Level 3
Level 3

Hi 

I am having a problem to figure out the reason of HSRP flapping on our Nexus 7000 pair running v6.2(10) . The problem comes time to time but after few seconds the flapping stops. below is the partial logs. Interestingly not all SVIs goes for HSRP flaps and the configuration timers etc are same on all
