10G will serialise packets 10x faster. Even if the average packet rate
is the same, you can have a 10x faster traffic rate on smaller
sampling intervals, which may exceed configured protection rates.

Broadcast, multicast or unicast storm-control? What rate? Have you
tried increasing the rate? Can you provide the logs of storm-control
taking the port down?
