Hello Guru,

You are right. Let me explain the scenario, hope it explain more details.

My tools and setup:
=================
A) FreeSwitch 1 ( hardware location in England co-location, internet
broadband, running skypeid for example: myuniqueskypeid1 )

B) FreeSwitch 2 ( hardware location in Belgium Office rack, internet
broadband, running skypeid for example: myuniqueskypeid2 )

C) My Laptop ( hardware location in belgium at home, internet broadband,
running skypeid for example: myuniqueskypeid99 )


Question & Answers:
==================
1. How do you generate calls?
B, C is generating calls

2. Where the calls go?
B, C calling to A (where B,C is trying to flood A)

3. Dialplan snippet you are using
- I am following our wiki, so there is nothing new
- 9999 is music play

4. Scripts you are using
- i am following our wiki, there is nothing new

5. Skypopen configuration (which skypeuser on which machine)

- A is running 30 instances of 1 unique skypeid and 100% implementation of
our wiki

- B is running 10 instances of 1 new skypeid (skypeid is not same as A)  and
100% implementation of our wiki
- B make calls to A to block few A channels to test capacity/cpu/ram/results
of fall down/bugs/crashes etc:

  // I am doing this in fs CLI manually but here what i am doing
  for ( i = 0; i < 40; i++ )
  {
     //
     // 5 or 6 Gets connected, the rest loop events cause that error
     // apply->
     //
     originate skypopen/ANY/myuniqueskypeid1**  9999
  }

 ** ( B keeps calling, when it keeps calling and A gets fail by not finding
the audio in/out or etc, then the problem gets started, instantly, CPU usage
grows to 90% where it should be in 10% and then the sound of cyclone/storm
gets born)

- C is running 1 another unique skypeid as regular skype instance with head
phone and microphone, for audio quality control



Hope i explain correctly. Where B from anywhere able to crash A production
switch, that's what happening in my case.

Thanks & Regards
