Thanks for your suggestion .We didn't see any STP TCN in our switches . The debug previously I have posted has packets from uplink. But we able to see lot of traffic from access ports (Connected with end machines) also.All the packets destined to IPV6 multicast address 33:33:FF:27:F3:C2.
I would recommend tracking down whoever owns that mac address: 33:33:FF:27:F3:C2 a show arp should do the trick
Now, try removing that host/server for a short time, see if the CPU improves (like to normal levels) worse case that MAC may be a security/virus beach considering it continually asks other hosts for data.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
