-----------------------------------------
Resolution: Fixed
> Cellar Hazelcast unresponsive when ETH Down
> -------------------------------------------
>
> Key: KARAF-4878
> URL: https://issues.apache.org/jira/browse/KARAF-4878
> Project: Karaf
> Issue Type: Bug
> Components: cellar-hazelcast
> Affects Versions: 4.0.5
> Environment: Redhat Linux 7.2, CentOS 7.2
> Reporter: Suresh Perumal
> Assignee: Jean-Baptiste Onofré
> Priority: Blocker
> Fix For: cellar-4.0.4, cellar-4.1.0
>
>
> 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.
