Description of problem:
The IPv4 tiebreaker code will do DNS resolution of the given address/hostname, even if the given parameter is already in dotted-quad format. If DNS is not responding, this can cause the IP tiebreaker to go offline erroneously, potentially causing a service outage if only one cluster node is online.
Version-Release number of selected component (if applicable): 1.2.37
