TCPPING fails to discover initial members if port-range is greater than 8
-------------------------------------------------------------------------

                 Key: JGRP-1183
                 URL: https://jira.jboss.org/jira/browse/JGRP-1183
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.8
            Reporter: Karthik Abram
            Assignee: Bela Ban

I also tested this with 2.10.0.ALPHA4

I have TCPPING configured this way:

<TCPPING timeout="3000"
             initial_hosts="localhost[11000],localhost[12000]"
             port_range="3"
             num_initial_members="1"/>

I notice that if I start up a process on port 11000 and then a second process that binds
to 11001, if the port-range is set to 3 (it seems any port-range less than 8) the
processes successfully find each other. When I set the port-range to 9 or higher, I see
GET_MBRS_RSP responses from the processes with each other's information but nothing is
discovered. I suspect some issue with threading/race-condition. Here is the trace log for
TCPPING with port-range = 50:
