So, when you try to run a server without Fritz, you get no problems? Is it actually happening all the time - interfering with your ability to run the server?

Usually it happens if your loading the bots up, loading the map up, or running other programs in windows that are hogging the CPU (sometimes just grabbing the dedicated server window and moving it around can do this).

Its harmless enough - it doesn't mean anything really, unless your seeing it all the time. And by all the time, I mean CONSTANTLY, where your screen is filled with them and never stops, EVER.

Then, you have a problem - maybe your rig is too low end, maybe you have some other program running in the background thats hogging up too much CPU, etc, etc.
