When using TCP_NIO, starting two nodes at the same time causes one of the nodes not to join group ------------------------------------------------------------------------------------------------- Key: JGRP-364 URL: http://jira.jboss.com/jira/browse/JGRP-364 Project: JGroups Issue Type: Bug Affects Versions: 2.4 Environment: linux 2.6 kernel x86_64 running java 1.5.0_06 Reporter: Matthew Todd Assigned To: Scott Marlow Fix For: 2.6 Attachments: test.xml, test1.bat, test2.bat, test2.xml, test3.bat, test3.xml I am testing a jgroups tcp_nio configuration using the draw demo.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 I am starting the draw demo like this; java -cp jgroups-all.jar:commons-logging.jar:concurrent.jar:jmxri.jar org.jgroups.demos.Draw -props test.xml 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
