You really don't need all this complexity to handle that. The main
thing is that you clear the storm state and adjust the storm counter
when the cpu goes offline (in case the state is ACTIVE).
When it comes online again then you can simply let it restart cmci. If
the storm on this cpu (or node) still exists then it will notice and
everything falls in place.
Keep it simple, really!
Thanks,
