I am using JGroups version: 4.0.2. I am testing with 4 nodes where each node
broadcasts request that it receives. I am using POSTMAN tool to send REST
request. I am sending REST request for CRUD operation to node 1. While the
CRUD request is being processed, I disconnected node 1 from the network. In
that case, view change was not triggered in node 1 and this in turn affects
application's behavior.

The following messages grows in node 1,

DEBUG:org.jgroups.protocols.FD_ALL: haven't received a heartbeat from node3
for 4130760 ms, adding it to suspect list
WARN:org.jgroups.protocols.FD_ALL: suspecting [node2, node3, node4]

The following message grows in other nodes than node 1,

WARN:org.jgroups.protocols.UDP: JGRP000032: 126.71: no physical address for
node1, dropping message


It was noted that the view change is received after connecting node 1 to
network again. 

What is the maximum time interval / number of heartbeat messages? How to
resolve / justify this?

Thanks in Advance :-)
