Why Running for some time it will be Auto Close
Start running without problem, but over time the server will automatically shut down
If you mean a server Pawn, maybe that is wrong will be compiled, or also a problem that I have seen in the console, when receiving several characters, as they crash in *,$,/,%,&, the server, well, this happens at a certain time, it does quickly, which is why I recommend that you put on your server auto kick players that contain these characters (this is when a player would do just this in connection to the server ).
I hope I've helped a little.
