Hello, I'm using JBoss AS 4.0.3 SP1 with JDK 1.5.10. I've setup a cluster of two JBoss instances with the partition name "DefaultPartition" and I pass the same IP Multicast address using the '-u' switch. However, the two JBoss instances don't see each other. I've not made any changes to the cluster-services.xml. When I start JBoss, I see the following log on each instance (I've blanked out the IP address): 2007-09-06 15:54:34,370 INFO [org.jgroups.JChannel] JGroups version: 2.4.1 2007-09-06 15:54:34,634 WARN [org.jgroups.JChannel] option GET_STATE_EVENTS has been deprecated (it is always true now); this option is ignored 2007-09-06 15:54:37,006 DEBUG [org.jgroups.JChannel] cannot get state from myself (xx.xxx.xx.xxx:32900): probably the first member Also, when I look at the DefaultPartition MBean from the jmx console, I see that CurrentView contains IP address of only one node. Could anyone point me to what could be going on? Thanks, Nitesh View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4081744#...
