Runtime DNS lookups for requests are performed only for forward (uri:host), t_relay() and other uri involving forwarding functions.
That would appear to have been it. Even though the uri:host was purely IP. But the odd part is that it would stay up for a few seconds and then the remote end would tear it down.
Correcting the system's DNS server entries (one of them had been replaced with a new server) corrected the problem. Just found it very odd since all the references in the config were by IP not name.
