2. A join group with itself only (from log file on A, never see B, C, D)

-------------------------------
Stack configuration ?
JGroups version ?
This is one of the most frequently tested scenarios (JGroups/doc/tests/GmsTests.txt), more
likely it is a network issue. Next time, could you please discuss this on the mailing
lists before opening a JIRA issue ?

<pbcast.GMS print_local_addr="true" join_timeout="5000"

</config>
All processes are seperate JVM under same machine. I just open different consoles for
testing failover and found there are group partitions.
I just know there is such forum in sourceforge. I will switch my focus to there see if
solution right there.
Thanks.

Bela Ban commented on JGRP-301:
-------------------------------
Works for me, even startup of all 4 processes at the same time. I made 2 changes though:
- Added bind_addr="192.168.5.2" to TCP
- Changed initial_hosts="192.168.5.2[8000]" in TCPPING
- Reduced port_range in TCPPING to 2
I assume 'localhost' is not set to the right IP address in your config
