Hi,
We have 4 jboss 4.0.4 instances in a cluster on two 64-bit windows 2003 servers. We are using NLB for load balancing.
Initially the instances failed to discover each other. I looked at the etc/hosts file and changed 127.0.0.1 to the IP/hostname of that machine. Then the instance on one machine recognized the intance on other machine. But, the two instances on the same machine still do not recognize each other for some reason.
Any help appreciated, thanks...
Do you have used the 'all' configuration?
Is the Multicast and UDP Port/Address the same at all nodes?
Is the partition name always the same?
Are you sure that a multicast works?
