Cisco Nexus 6k - Debugging COPP ICMP - Switch Swamped

I am trying to determine what is the source of all the copp system violations/drops.
The switch Nexus 6k is processing traffic just fine. But pinging it directly is resulting
in drops which I presume are associated with these violations. Would a debug copp
give me insight into what's sending so much traffic? The CPU is only at 10% but
I need the device to respond to ping again and I have no idea what's hammering it.
If I run the debug copp - is there any danger that the debug could cause a problem
with the operation of the switch at the control plane or the data plane?: Any other
thoughts are greatly appreciated.
