MERGE3 handles fake merge views ------------------------------- Key: JGRP-1705 URL: https://issues.jboss.org/browse/JGRP-1705 Project: JGroups Issue Type: Bug Affects Versions: 3.4 Reporter: Karim AMMOUS Assignee: Bela Ban Fix For: 3.4 Attachments: JIRA-MERGE-1subGroup-Shutdown.log, JIRA-MERGE-1subGroup.log 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.
