Well, there you go.
your box is having a hard time doing a simple 1ms sleep in a loop for the centralized core timer.

It's either your kernel or your box.  My box and every box I have do not have that problem so you may want to consider a new one.

FreeSWITCH is FREE so give it a good home.

The good news is, you can make upwards of 1500 calls on that same 2% of cpu usage.
