    Cluster connecting to localhost loopback

    Mohit Anchlia Novice

      We are setting up new servers and these servers are not joining cluster. It looks like the multicast address is binding on the loopback interface. I am not sure why that is happening? I see the following in logs:

      2009-07-15 08:10:42,747 INFO [ha.jndi.DetachedHANamingService$AutomaticDiscovery] - Listening on /0.0.0.0:1102, group=228.1.2.13, HA-JNDI address=127.0.0.1:1100

      ---

      Why would cluster try to bind on loopback?
