[jboss-jira] [JBoss JIRA] (JGRP-2128) MERGE3: incorrect merge

[Anjith Paila (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-2128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13320381#comment-13320381 ] 

Anjith Paila commented on JGRP-2128:
------------------------------------

We have a 3 node Infinispan cache cluster with numOwners=2.  We started the nodes one by one and the cluster got formed correctly with 3 nodes. Then we disconnected one of the node from the network and connected it back. But this started creating incorrect merges instead of forming the original 3 node cluster. I've added the logs of all 3 nodes and they have trace mode enabled.
