[jboss-jira] [JBoss JIRA] Closed: (JGRP-392) disconnect() hangs forever on second client of group

disconnect() hangs forever on second client of group ---------------------------------------------------- Key: JGRP-392 URL: http://jira.jboss.com/jira/browse/JGRP-392 Project: JGroups Issue Type: Bug Affects Versions: 2.4 Environment: Windows XP. java version "1.6.0" Java(TM) SE Runtime Environment (build 1.6.0-b105) Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing) "UDP(mcast_addr=239.10.10.10;mcast_port=17000" + ";ip_ttl=8;" + "mcast_send_buf_size=150000;mcast_recv_buf_size=80000):" + "PING(timeout=2000;num_initial_members=3):" + "MERGE2(min_interval=5000;max_interval=10000):" + "FD_SOCK:" + "VERIFY_SUSPECT(timeout=1500):" + "pbcast.NAKACK(gc_lag=50;retransmit_timeout=300,600,1200,2400,4800):" + "UNICAST(timeout=5000):" + "pbcast.STABLE(desired_avg_gossip=20000):" + "FRAG(frag_size=4096;down_thread=false;up_thread=false):" + "pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;" + "shun=false;print_local_addr=true):" + "pbcast.STATE_TRANSFER"; Reporter: Oyvind Eikeland Assigned To: Bela Ban Fix For: 2.5 Attachments: coordinator.log, member.log Quite often, but not every time, when member 2 (not the coordinator) is disconnecting from the group, it will wait forever. This may be some configuration or network issue, but it would be very useful if a timeout could be specified in the JChannel.disconnect() method to get around this problem. Members are running in separate JVMs. when a member/client is leaving a channel, we're calling these methods: - channel.disconnect(); - channel.close(); This method is called from disconnect() today: disconnect_promise.getResult(); // wait for DISCONNECT_OK Instead, disconnect_promise.getResult(timeout); should be called. It does not seem to be possible to configure this timeout in the protocol stack
