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

                 Key: JGRP-666
                 URL: http://jira.jboss.com/jira/browse/JGRP-666
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.6.1
         Environment: Windox XP  Sun JDK 1.5 ; Jgroup 2.6.1
            Reporter: Liu Torr
         Assigned To: Bela Ban
            Priority: Critical


Run this test case in three window that we can all them as A, B, C. after starting all these tree, then stop C first and resart it quickly, then B, and A.

public class TestJoin {

	public static final String DEFAULT_PROTOCOL_STACK=
		"UDP(mcast_addr=228.8.8.8;mcast_port=45566;ip_ttl=32;mcast_send_buf_size=150000;" +
		"mcast_recv_buf_size=80000):" +
		"PING(timeout=2000;num_initial_members=2):MERGE2(min_interval=5000;max_interval=10000):" +
		"FD_SOCK:" +
		"FD(timeout=10000;max_tries=5;shun=true):" +
		"VERIFY_SUSPECT(timeout=12500):" +
		"pbcast.NAKACK(gc_lag=50;retransmit_timeout=300,600,1200,2400,4800;max_xmit_size=8192):" +
		"UNICAST(timeout=300,600,1200,2400):pbcast.STABLE(desired_avg_gossip=20000):" +
		"FRAG(frag_size=8096;down_thread=false;up_thread=false):" +
		"pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;shun=false;print_local_addr=false)";
	
	public static void main(String[] args)
	{
		NotificationBus bus;
		try {
			bus = new NotificationBus ( "test", DEFAULT_PROTOCOL_STACK );
			bus.getChannel ().setOpt ( Channel.LOCAL, Boolean.FALSE );
	        bus.start ();
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		while(true)
		{
			System.out.println("******************************************");
			try {
				Thread.sleep(5000);
			
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
	}
}



And after that, the A and B will be blocked for joining the group. here is hte console output:
(it should join the group and output the ****************)

I have used Jgroups 2.2.9, and the same problem happened (different console output with more message trace information.).
