High traffic to 224.0.0.0/24 breaks a *lot* of kit. It's not just Cisco 
or Catalyst.

Applications emitting lots of traffic to this range should be considered 
no different to applications emitting lots of traffic to the broadcast 
address; they're broken and should be disconnected from the network.
