Alright My server runs fine, except every once in awhile everyone in the server starts lagging out and they get pings of 999 they have to disconnect and reconnect and then the pings go back to normal.
I have had my server set up in the past with no lag problems, it just started recently.
Any Suggestions?
Either your CPU or your Internet connection is getting overloaded.
Don't play on the same computer that is the server, and set sv_maxrate 4000.
