but server side on samp

but sometimes the counter get wrong...
why?
there is any way that OnPlayerStreamIn/OnPlayerStreamOut can bug onplayerdisconnect, setplayerposs or somehow else?

or there is something wrong on my script?

script:

public OnPlayerStreamIn(playerid, forplayerid)
{
    // se nao ta logado nem vai pra baixo
    if(isLogged[playerid] == false) return 1;
    if(isLogged[forplayerid] == false) return 1;
    // anti double stream
    if(isPlayerStreamed[playerid][forplayerid] == true) return 1;
    isPlayerStreamed[playerid][forplayerid] = true;
    // atualizar txds pedslots
    if(gSpectateID[forplayerid] == 65535) {
        pedslots[forplayerid] += 1;
        KillTimerEx(timerUpdatePedSlots[forplayerid]);
        timerUpdatePedSlots[playerid] = SetTimerEx("UpdatePedSlotsTxd", 1500, false, "i", forplayerid);
    }
    return true;
}
public OnPlayerStreamOut(playerid, forplayerid)
{
    // anti double stream
    if(isPlayerStreamed[playerid][forplayerid] == false) return 1;
    isPlayerStreamed[playerid][forplayerid] = false;
    // 
    if(gSpectateID[forplayerid] == 65535) {
        if(pedslots[forplayerid] > 0) pedslots[forplayerid] -= 1;
        KillTimerEx(timerUpdatePedSlots[forplayerid]);
        timerUpdatePedSlots[forplayerid] = SetTimerEx("UpdatePedSlotsTxd", 1500, false, "i", forplayerid);
    }
    return true;
}
public UpdatePedSlotsTxd(playerid) {
    if(isLogged[playerid] == false) return 1;
    // atualizar ped slots
    new string[32];
    format(string, sizeof(string), "peds: %d"
        , pedslots[playerid]
    );
    PlayerTextDrawSetString(playerid, txdPedSlots[playerid], string);
    PlayerTextDrawHide(playerid, txdPedSlots[playerid]);
    PlayerTextDrawShowEx(playerid, txdPedSlots[playerid]);
    return 1;
}
