      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.
