You must use different ports for HLstatsX:CE daemon in game server installations:
srcds server #1 - "logaddress_add <IP>:27500" in it's server.cfg,
srcds server #2 - "logaddress_add <IP>:27501" in it's server.cfg,
srcds server #3 - "logaddress_add <IP>:27502" in it's server.cfg, etc.
And daemon is usually started as "run_hlstats start <# of daemons> <first port number> <port increment number>", so in this case:
"run_hlstats start 3 27500 1"
