-------------------------------------------

[~ethompson] Could you please provide us some details on your deployment? At least we would need to know the {{dig}} command result and have some debug logs from {{org.jgroups}} category.

> This is a follow-up to JGRP-2296 - which changed `DefaultDNSResolver.java` to preserve the port for SRV records.  While that change is working as desired, `DNS_PING.java` is not using the port when doing member discovery.

> 2018-11-29 21:37:41,562 DEBUG [org.jgroups.protocols.dns.DNS_PING] (thread-4,null,null) 982d38761cba: sending discovery requests to hosts [172.29.11.50:27106, 172.29.11.50:27105] on ports [7600 .. 7600]
> {noformat}
> Since the port was found via the SRV record, it should be used instead of the *transportPort* port.
