I set follow valut in server.cfg
l4d_maxplayers 18 //code1
sm_cvar z_max_player_zombies 8 //code2
sm_cvar survivor_limit 8 //code3
After start "Win" server,it allow 8 survivors , 8 player infected and 2 spectator and won't reset above value.
But the same way in linux isn't workable!!
After start "Linux" server,code2 and code3 always on lock.
did I mention clearly?
