Steps to Reproduce



Not applicable


Root Cause



Two of the eight nodes in the environment reside on machines which have more than one NIC and each NIC has a different ip address.
.
On these two nodes Hazelcast is choosing an ip different from the rest of the members of the Hazelcast cluster.

Resolution



The DSS Pega-Engine • prconfig/cluster/hazelcast/interface/default was defined with value <ip address>.*
so that all nodes in the environment will use the same ip address when joining the Hazelcast cluster.
