We've been noticing not all stats are being recorded properly. After doing some research it looks like this was most likely caused by an overload on the hlstatsx log daemon. The overload was caused by the L4D2 servers streaming an incredible amount of logs from its games.

We've now split up the hlstatsx daemons in 4 separate processes, 1 for each L4D2 servers, and 2 for the rest of the TF2 servers.

Please post here if you notice any new issues or if you notice the stats are indeed counted better.

Ah, that's the reason why many of my kills are missing in the stats.

New updates to hlstatsx should be coming "soon".
