Granted I'm swinging in the dark here, but you try localhost:8005 to see if the admin port works yet? or just 8080?
Are there logfiles that you can view? Looks like you get the server up and listening, when something tries to connect that's when the port closing?
First step that I would try is change the port to something else other than the one for web traffic see if that resolved it. Best of luck though.
