             Summary: Graceful concurrent leaving of coordinator(s) leaves the cluster with wrong views
                 Key: JGRP-2293
                 URL: https://issues.jboss.org/browse/JGRP-2293
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 4.0.14
            Reporter: Radoslav Husar
            Assignee: Bela Ban
            Priority: Critical


JGroups does not handle concurrent leaving of nodes correctly. This is a typical use case in cloud environment when scaled down with an autoscaler/manually which we need to handle.

A simple test can be devised which fails first n (where n>1) nodes from a cluster.
