Error: Can't set headers after they are sent

Maybe a network problem. The application cannot call itself on port 8082. Can you check your network config?

Tried changing the port in the default.yml, then I can start the server, but its crashing after I call it, see the output:

Is it possible that you are trying nodejs 0.9?
It seems to work only with 0.8 :-)
