I think you also shouldn't use the ipaddr switch: That's for clients, and makes no sense on a server. Perhaps it will not crash if you leave that switch out.
Me, for my hosting, I use:
dom2 -imqsST --port XXXX GameName
I tried using your command line and it still exits after a few seconds. I played around with the different options and its the quickhost that is making it quit. If I leave -q in it will exit, but if I take it out it will run normally.
Any idea why quickhost would make it exit? Isn't it just supposed to generate the next turn and sit there?
Hahah! Yeah I did have only one player cause I was just testing out the multiplayer stuff. I thought I had all the command line settings right so that must be it. I'll try it again with 2 clients hopefully that should work.
