I believe that you do not increase the value is used in while and it's an infinite loop; hence it makes the server to stop.

I'd recommend you to use for loop but in case you want to use while, it can also be done like:

pawn Код:

new 
    i = -1;

// increasing i by 1 and it returns the new value - it basically starts as: while(0 < MAX_PLAYERS) and it is increased later on..
while (++i < MAX_PLAYERS) 
{
    //do stuff here
}
