Dennis Reed updated JGRP-1198:
------------------------------

    Steps to Reproduce: 
To reproduce, start two members using TCP/TCPPING within TCPPING.timeout of each other (using 127.0.0.1:7600 and 127.0.0.1:7650 below).
When the first instance establishes itself as the master, it kills the valid connection to the second instance.

After TCPPING.timeout, on the first instance:
    TRACE [org.jgroups.protocols.pbcast.GMS] I (127.0.0.1:7600) am the first of the clients, will become coordinator
    DEBUG [org.jgroups.protocols.pbcast.GMS] [local_addr=127.0.0.1:7600] view is [127.0.0.1:7600|0] [127.0.0.1:7600]
