>             Project: Karaf
>          Issue Type: Bug
>          Components: cellar-hazelcast
>    Affects Versions: 4.0.5
>         Environment: Redhat Linux 7.2, CentOS 7.2

> Cluster is configured with 2 Nodes. They are up and running.
> As part of fail-over scenario simulation. We are trying to test "ETHERNET down scenario"
by running "/etc/sysconfig/network-scripts/ifdown eth0" command on the first node.
> During this scenario we are shutting down the first node where the ETH is  down by using
monitoring scripts(in-house scripts). The second node(Among those two nodes) is kept alive.
> Second Node's Hazelcast is not accessible for more than 15 minutes. We are getting bellow
exception and no operation related to Hazelcast is working. Applications whichever uses hazelcast
kept frozen.
