Re: Call slamming

  Anyone have any thoughts or suggestions on how to limit the rate of incoming calls per second? 

  I tried reducing the value of "ListenQueueLength" as far down as 1 with no positive effect. 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).

    One more thing, I only want to slow the rate of calls per second. I don't want to limit the total number of concurrent calls.

 with hundreds of calls per second and it brings the gatekeeper down almost to a complete halt.

  Is there any way to control the incoming rate of calls? In the config file i see the following parameter:

  ListenQueueLength=1024

  If 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?
