OK, I'll change the mcast_addr in MPING for this test. Can you see if changing either
bind_addr or mcast_addr in MPING fixes this issue? E.g. set bind_addr to a non-loopback
address.

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,
