Hello,
My server have 32 slot but when is full , 32/32 statistics only registring 24 player's.
I don't know why and how fix it please help me if this have a solution.
My server : http://www.gametracker.com/server_info/5.83.43.11:27015/
Thank you !

It is currently showing 29 players.
Server scanning is not constant, nor 'live'. The displayed results will always be at least 4-8 minutes behind the server.

Same problem here look it's 31/32 but on the statistic line show 24 , and don't jump over 24 , please help me to fix it http://www.gametracker.com/server_info/89.40.104.242:27015/

I have just explained it.
That server is now displaying 29 players.
There is nothing to fix.
Go play. Kill someone (in game) and be happy.

I understund but i say on HISTORICAL DATA, sometime stay 3 hour 32/32 and stuck the line on 24 , like now you see 29 and 32 , see afer 2-3 hour the line. I explain the problem and i need help to fix it.

For the last time; there is nothing to 'fix'.
The historical graph is based upon average players over a period of one hour, and is updated after the previous hour results have been calculated.

It will never be a current display. The clue is in the word 'historical'.
