My Counter Strike: Global Offense game automatically restarts my computer before it finishes loading up, I don't see a loading screen or a menu screen.
Outside of the game, malicious software such as trojans and root-kits can cause this behaviour so scan your computer to be sure.
Debug allows you to see the output of the server directly to your terminal allowing you to diagnose any problems the server might be having.
Linux GSM can monitor the game server by checking that the proccess is running and querying it. I have several years experience with Linux servers and enjoy learning and working on Linux projects.
Game servers traditionally are not easy to manage yourself.
Admins often have to spend hours just messing around trying to get there server working.
