Does anybody have anything to suggest as a solution to control the rate of calls per second?

Thanks for the reply but completely blocking the customer isn't what I want to do. I would like to control the rate of calls in some manner that allows me to discard new connections when calls per second exceed a certain rate or when a certain number of calls are in queue that have not yet undergone translation or some other means to control rate of call flow.

Calls coming in continue to slow the GK to almost a complete halt as the queue flushes at rates of 100 - 200 calls per second. Faster CPU doesn't help (quad opteron).

In the config file i see the following parameter:ListenQueueLength=1024If I reduce that number to, say, 50, would that help?Would reducing that number cause any other issues I should consider?Is there another way I can limit the incoming connection queue to prevent being slammed?__________________________________________________
