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.
- 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.
