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

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: | <config> | <TCP_NIO | bind_addr="192.158.70.200" | recv_buf_size="20000000" | send_buf_size="640000" | loopback="false" | discard_incompatible_packets="true" | max_bundle_size="64000" | max_bundle_timeout="30" | use_incoming_packet_handler="true" | use_outgoing_packet_handler="true" | down_thread="false" up_thread="false" | enable_bundling="true" | start_port="7800" | end_port="7800" | use_send_queues="false" | sock_conn_timeout="300" skip_suspected_members="true" | | | /> | | <MPING timeout="2000" num_initial_members="3" mcast_addr="229.6.7.8" | | bind_addr="192.158.70.200" down_thread="false" up_thread="false"/> | | <MERGE2 max_interval="100000" | down_thread="false" up_thread="false" min_interval="20000"/> | <FD_SOCK down_thread="false" up_thread="false"/> | | <VERIFY_SUSPECT timeout="1500" down_thread="false" up_thread="false"/> | <pbcast.NAKACK max_xmit_size="60000" | use_mcast_xmit="false" gc_lag="0" | retransmit_timeout="300,600,1200,2400,4800" | down_thread="true" up_thread="true" | discard_delivered_msgs="true"/> | <pbcast.STABLE stability_delay="1000" desired_avg_gossip="50000" | down_thread="false" up_thread="false" | max_bytes="400000"/> | <pbcast.GMS print_local_addr="true" join_timeout="3000" | down_thread="true" up_thread="true" | join_retry_timeout="2000" shun="true" | view_bundling="true"/> | <!-- <FC max_credits="2000000" down_thread="false" up_thread="false" | min_threshold="0.10"/> | <FRAG2 frag_size="60000" 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 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984074#...
