I don't think this works: an ifconfig down/up is not something that a socket would survive ! Can you use IP Bonding ? I'll try this out on my Linux cluster though to see what the behavior is > For an unknown raison node A stop receiving Multicast from B resulting > on an unstable cluster were members could not join the same cluster > anymore.
