Good. I am unsure if we ever can hit 0 bad conn. We can take a look on the
flash.vg.no servers. They serv alot of traffic also if I reduce the
servers from 4 to 1. The bad conn number there is of interest.

Okay. I wanna ask Åge Røbekk to take a look next time we pound it with
traffic. He has experience with finding/fixing problems like this. We hit
a wall like this on flash.vg.no once. And he tuned some parameters that
fixed it.
