[Sammi Ting (JIRA)]

    [ http://jira.jboss.com/jira/browse/JGRP-301?page=comments#action_12343004 ] 
            
Sammi Ting commented on JGRP-301:
---------------------------------

Version: 2.4CR1

All processes use same configuration:

<config>
    <TCP start_port="8000" loopback="true" send_buf_size="100000" recv_buf_size="200000" enable_diagnostics="false"/>
    <TCPPING timeout="3000" initial_hosts="localhost[8000]" port_range="4" num_initial_members="4"/>
    <FD timeout="2000" max_tries="4"/>
    <VERIFY_SUSPECT timeout="1500" down_thread="false" up_thread="false"/>
    <pbcast.NAKACK gc_lag="100" retransmit_timeout="600,1200,2400,4800"/>
    <pbcast.STABLE stability_delay="500" desired_avg_gossip="20000" down_thread="false" max_bytes="40000000" up_thread="false"/>
    <VIEW_SYNC avg_send_interval="60000" down_thread="false" up_thread="false" />
    <pbcast.GMS print_local_addr="true" join_timeout="5000" join_retry_timeout="2000" shun="true"/>
</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.

> There are 4 processes named A, B, C, D which should be join in a same group
> Startup Sequence: A->B->C-D
> Scenario:
> 1. Start up A, with 0.5-1 sec time later, immediately start B, C, D
> 2. A join group with itself only (from log file on A, never see B, C, D)
> 3. B, C, D joined group together (from log files on B, C, D, never can see A)
> 4. Wait for long time A still in a single group
