Looks like the machine you are running jboss server on is a part of a network and other machines on the same network have it installed. This would generally not cause any issue if they were using different partitions. By default when you start jboss, it starts in default partition, and all other server instances running on the network that have not specified their partition name would join that default partition. Due to this, the messages are relayed to every server in the partition. To avoid this, you might need to specify the partition name and mcast address for the machine. Hope that helps. ---A person who sees the world in his fifties the same way he saw it in his twenties has actually wasted his 30 years.
