I suggest you to Kick all the players from the server when you're restarting it, because that's the best secure way to make sure that the stats are being saved.

pawn Код:

foreach(Player, i)
{
if(IsPlayerConnected(i))
{
Kick(i);
}
}

put that in your /gmx cmd. I also recommend you to make /savestats so the player can save all his statistics in-game.
