KMIP server
External Key-manager

Issue

Connection to KMIP server for encryption seems to drop and reconnect in a span of a second, according to EMS logs, for some but not all the nodes in the cluster.
 
Example of what is seen on EMS:

Sat Sep 19 07:29:53 UTC [node-n1: mgwd: km.keyserver.notavailable:alert]: The external key management server "10.1.2.3:5696" is not available for Vserver "vserv001", status: "unknown".
 
Output of 'security key-manager external show-status' indicates kmip server is not accessible by node-n2:
cluster::> security key-manager external show-status
