[jboss-user] [Clustering/JBoss] - jgroups tcp_nio configuration

[mjtodd]

I have a jgroups configuration successfully working using tcp. I am trying to change this to tcp_nio as I understand this will give better performance on large clusters. I am testing my configuration using the jgroups demo draw program. If I start up my 3 nodes one by one then everything works fine. However if I start up node 1, then attempt to start node 2 and 3 in parallel then only node 2 will work. Node 3 will be isolated and not see the other nodes and logs the following message:

org.jgroups.protocols.pbcast.ClientGmsImpl join
  | WARNING: join(192.158.70.200:7802) sent to 192.158.70.200:7800 timed out, retrying
  | 

Here is the configuration for one of my nodes:

  |     <!-- <FC max_credits="2000000" down_thread="false" up_thread="false"

  | <pbcast.STATE_TRANSFER/>
  | <!--    <pbcast.FLUSH down_thread="false" up_thread="false"/>-->
  | </config>
  | 
Node 2 and 3 have the same configuration except the port they bind to has been changed

Any help would be appreciated
