You guys are right. I see now the error of my ways. I was forgetting the fundamental difference that the second Orion process runs as a second VM. I was trying to recreate a setup I had often done with other webservers but with them I always used the same 'process' with different virtual hosts. Many of them never required restarting because they were just webservers and not application servers as Orion is.
With our development Orion setup we often make changes that require a restart and I was trying to avoid the restart of one Orion from affecting all the sites being served by that box.
The only reason I was trying to use the same IP and port was because I did not understand why it should not work. Now I do.
thanx,
Larry

Subject: RE: Running two instances of Orion on the same IP and port
This has nothing to do with Orion per se. It's a fact of life that only
one process at a time can bind to a port on a host. For example, say
you had Orion bound to port 25 along with your email server. Who would
try to handle SMTP requests to port 25? Orion or the mail server? The
answer is whoever bound the port first. And once a process has bound to
a critical port (such as a Web server binding to port 80), it usually
doesn't "let go" until the process is stopped.

Subject: Running two instances of Orion on the same IP and port
Orioners,
Has anyone ever tried to run two instances of Orion on the same machine,
IP and port. What I am trying to do is have a second instance of Orion
listen to only certain virtual hosts (headers) and the first pick up any
unknown or blank headers.
The reason for us doing it this way is to have a test installation of
Orion that will be restarted often and a second 'stable 'installation
that will run some ancillary sites for our internal network.
I know that binding a second IP to the box and having the second Orion
listen on that IP would probably work. Is there an obvious reason that
the way I am attempting always gives me an "Error starting HTTP server:
Address already in use" error on the second instance?
thanx,
Larry
