            Description

            Under some conditions, MERGE3 handles fake merge views. After "merge", number of members that form the cluster still the same and the mergeView contains only one subgroup.

            Scenario:

            • Form a large cluster (1115 mbrs)
            • Enable MERGE3 TRACE logging level on coordintor member (172.29.190.5)
            • Reboot one machine (172.29.190.5) hosting 7 JVMs
            • Coord install a new view with 1108 mbrs.

            When new members join the cluster we observe a merge view formed by only one subgroup.

            Coordinator log file was attached to this JIRA.
