I have a server with 100+ players sometimes 200+. If you have a very good game hosting (a good processor) will be just a piece of cake, because yeah maybe the public will be called 5 times ~ in the same time, or the public will be called by the same playerid two times in 1 sec. But you can get out it, using a variable as in the following example:

PHP код:

new smmh[MAX_PLAYERS];
public OnPlayerConnect(playerid)
{
   smmh[playerid]=0;
   return 1;
}
public OnPlayerDisconnect(playerid)
{
  smmh[playerid]=0;
  return 1;
}
forward ShowMeMyHealth(playerid); 
public ShowMeMyHealth(playerid) 
{ 
    GetPlayerHealth(playerid,health); 
    printf("HP in HPBar %f",health); 
    smmh[playerid]=0;
} 
public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid, bodypart) 
{ 
    Account[playerid][Health] -= amount; 
    SetPlayerHealth(playerid,Account[playerid][Health]); 
    new Float:health; 
    printf("HP in Acc %f",Account[playerid][Health]); 
    if(!smmh[playerid]){ smmh[playerid]=1; SetTimerEx("ShowMeMyHealth",1000,"i",0,playerid); } 
        return 1; 
} 


Try it, I use timers in order to detect Invulnerable, for instance I check and every each 10 second each player using the following algorithm: I set its hp-1 and after 1 sec I check if its hp is -1 if it is not it means that it use invulnerable.. and it works.. (I also check about ping etc..)
