socket error creating endpoint on localhost

I am trying to get back into using Ice, it has been a long time. I downloaded v 3.3, and wrote a very simple server application that inherits from Ice.Application. I pass in the path to the config.server file, and try to call

Ice.ObjectAdapter adapter =

My server.config is right out of Hello World. The line that configures my endpoint is:

# The server creates one single object adapter with the name
# "Hello". The following line sets the endpoints for this
# adapter.
foo.Endpoints=tcp -h -p 10000

but I always get this stack trace complaining about trying to create more than one listener on any given port/socket:

ing to bind to tcp socket ]

I rebooted the machine I am testing on, and I see no competing processes trying to use port 10000. I tried changing the port too, it does not help. If anyone has experienced an issue like this I would appreciate any assistance you can render.

    Hi George,

    It's hard to tell what's wrong here. Can you run any of the Ice for .NET demo on this system (for example the hello demo)?

    If your server is very simple, the easiest could be to post the full source here (including Slice and config file): we should be able to spot the problem quickly!
