Two subgroups don't merge when one of the hosts in TCPPING(intial_hosts=...) list is not accessible --------------------------------------------------------------------------------------------------- Key: JGRP-260 URL: http://jira.jboss.com/jira/browse/JGRP-260 Project: JGroups Issue Type: Bug Affects Versions: 2.2.9.2 Environment: Debian GNU/Linux 2.4.27, JDK 1.5.0_05 Reporter: Tomasz Skutnik Assigned To: Bela Ban Attachments: Test1.java When I run client program (see attachment) with following command: - on host h1: $ java -cp \ jgroups-all-2.2.9.2.jar:concurrent.jar:commons-logging-1.1.jar:\ classes test.Test1 "h1" "h1[7800],h3[7800]" - on host h2: $ java -cp \ jgroups-all-2.2.9.2.jar:concurrent.jar:commons-logging-1.1.jar:\ classes test.Test1 "h2" "h1[7800],h3[7800]" And host "h3" is known (listed in /etc/hosts) but physically turned off both hosts (h1 and h2) create two disjoint groups instead of one merged group. And on host "h2" following warnings/errors are logged: 2006-07-11 08:56:07 org.jgroups.protocols.pbcast.CoordGmsImpl$MergeTask run WARNING: merge responses from subgroup coordinators <= 1 ([sender=172.16.195.131:7800, view=[172.16.195.131:7800|0] [172.16.195.131:7800], digest=172.16.195.131:7800: [0 : 5]]).
