Okay, this is really starting to get frustrating.  Googling this error
gives me the strong impression that the timeout here is a DNS timeout,
but I have no clue how to get our DNS servers to respond to something
like  I tried changing it to "::1" but it just moved the
error up to when starting up TCP Listeners instead.  It also said that
I should be giving in "tuple form", but i'm not sure what
that means at the moment.

I replaced Erlang v5.6.5 R12B-5 (as included in the official
installation) with v5.7.3 R13B02-1 (what the server that works is
using) with no effect.  I copied the rabbitmq_server.1.7.0 folder
(with the installed plugin) from the server that works with no
effect.  Same with wiping the database folder.

ProcessExplorer trace shows no registry or file activity during the
"timeouts", the next action after the first one is a load of
stomp.beam, the action after the second is a write to the log file.
The only attempt to access %APPDATA% is to write a file
named .erlang.cookie - no other file or folder existence check is

Modifying the stomp_listener line to change the ip address to
or scramble to a dummy port has no effect (is this thing hardcoded to
{"",61613} or something?)

The fact that this is working on the testbed but is throwing a tantrum
on the server it might actually have value on means that it's an
environmental fault of some kind, either a file I haven't found or a
different server setup that is causing confusion.

Maybe I'll try to get this working sometime next week - I'm running
out of ideas.  I don't have anything on me that I can see to intercept
WINSOCK calls either.

Any suggestions on where to go from here?  Dumping my 1.7.1 startup
trace here...

Unfortunately, If it hadn't taken two weeks of my boss's time to try
to get it working I think I would be more amenable to sneaking
something like that out.  As it is I'd like to have something to show
first before dealing with that.  I can bellyache some more about the
kinds of changes I needed to make, but I'm not sure how constructive
that would be.
