Cluster issue

[chrlon]

Hi, I'm trying to set up a hornetQ stand alone cluster with two nodes but when I start the second node the message below shows up repeatedly on both nodes

[hornetq-discovery-group-thread-dg-group1] 14:42:49,158 WARNING [org.hornetq.core.cluster.impl.DiscoveryGroupImpl]  There seem to be more than one broadcasters on the network broadcasting the same node id

thats because they are both using the same journal, maybe when u copied the config u copied the journal too, just delete it and everything will work

Hi Andy,

I am facing the same issue despite of removing the journals from the data/hornetq/journal.

I am using HornetQ2.0.

Is there any possibility that the names of the discovery group being the same on different servers leading to this problem?

Regards,

Joydeep
