In EAP7 image JGroups TCP stack configuration, KUBE_PING has extra socket-binding configuration for MPING. It's most likely someone modified MPING to KUBE_PING but forgot to remove the socket-binding.

<protocol type="openshift.KUBE_PING" socket-binding="jgroups-mping"/>
I think the KUBE_PING doesn't use the socket-binding so we need to remove it to avoid confusions.
