[Paranoja]

I have created my own Mysql based Register/Login system, and since 2 players connnect at the same moment to the server, my server just crushes without any of error (Don't Send). As far as i know, it's because of AutoLogin system, because when i take it off and 2 people connects everything is ok, but when i add it, this thing happens. My Code:

Код:

public OnPlayerConnect(playerid) {
	logged[playerid] = 0;
	new nickname[MAX_PLAYER_NAME];
	new ipaddress[16];
	new query[256];
	new query1[256];
	new connect[128];
	GetPlayerName(playerid, nickname, MAX_PLAYER_NAME);
	GetPlayerIp(playerid, ipaddress, sizeof(ipaddress));
	format(query, sizeof(query), "SELECT * FROM `users` WHERE `nickname` = '%s' LIMIT 1", nickname);
	format(query1, sizeof(query1), "SELECT * FROM `users` WHERE `nickname` = '%s' AND `ipaddress` = '%s' LIMIT 1", nickname, ipaddress);
	format(connect, sizeof(connect), "%s prisijыngл prie serverio.", nickname);
	samp_mysql_query(query);
	samp_mysql_store_result();
	if (samp_mysql_num_rows() == 0) {
		SendClientMessage(playerid, COLOR_USER, "|VARTOTOJAS|: Toks vartotojo vardas yra neregistruotas. Uюsiregistruoti galite serverio tinklalapyje.");
		SendClientMessage(playerid, COLOR_SERVER, "http://samp.ruined.lt");
		Kick(playerid);
	}
	samp_mysql_free_result();
	samp_mysql_query(query1);
	samp_mysql_store_result();
	if (samp_mysql_num_rows() == 1) {
		SendClientMessageToAll(COLOR_HIDDEN, connect);
		SendClientMessage(playerid, COLOR_USER, "|VARTOTOJAS|: Sveika/s sugryюus/жs б serverб.");
		logged[playerid] = 1;
	}
	if (logged[playerid] == 0) {
		SendClientMessageToAll(COLOR_HIDDEN, connect);
		SendClientMessage(playerid, COLOR_USER, "|VARTOTOJAS|: Toks vartotojo vardas jau yra uюregistruotas. Naudokite komandа /prisijungti [slaptaюodis] norлdami prisijungti.");
	}
	return 1;
}

Thank you for your help.
