More info:

I left 2 "broken" JBoss instances in the cluster and the Brno lab admin noticed that there has been going 20 mbps traffic to everyone in the same virtual LAN. As can be seen from the images, 2 nodes are sending 10 mbps traffic  through multicast.

10mbps is quite a lot if we expect them to only send heartbeats :)
