Server infinite looping (not crash)

[SergeyShorokhov]

Noticed this afternoon that the server does not respond to _A2S__ requests, decided to check from the console - as a result - HLDS costs hung (loop).

Why say htop: Lastest HLDS console log:

Start Line: Start Line: ./hlds_linux -game czero -strictportbind +ip <_SOME_SERVER_IP> -port 27025 +clientport 27005 +map de_dust2_cz -maxplayers 16 version
