---------------------------------------

                 Key: JGRP-620

    Affects Versions: 2.5.1
         Environment: RHEL4 64 bit: Linux svr5 2.6.9-42.0.10.ELsmp #1 SMP Fri Feb 16 17:13:42 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

         Assigned To: Bela Ban
         Attachments: stacktrace.txt, tcp-config.xml

RpcDispatcher.callRemoteMethods() hangs, while there is a lot of member churn at the time (4 servers starting into a cluster of 4). 1 of the 4 server starting up is hung with the attached stack trace.

-------------------------------------------------------------------
channel=new JChannel(jgroups_config_file);
channel.setOpt(Channel.AUTO_RECONNECT, Boolean.TRUE);
channel.addChannelListener(this);
		
//TODO: verify these startup params
//NOTE: deadlock detection leaks memory as of 2.5b2, do not use
disp=new RpcDispatcher(channel, null, this, this, false, true);
		
//force connect
channel.connect(clusterName);

MethodCall mc = new MethodCall("remoteBroadcastAvailability", new Object[]{peer,sequence,serviceStatus,rotationStatus}, new Class[]{Address.class,Long.class,ServiceStatus.class,RotationStatus.class});

disp.callRemoteMethods(channel.getView().getMembers(), mc, GroupRequest.GET_ALL, 0);
