A program should not be visible in "top" when idle. That's my point.

I guess if you insist, you have 4 bad boxes with 4 bad kernels, and I bet none of them are Centos 5.3 if you can reproduce it on a box I can visit (Centos 5.3 would be nice), put in my ssh key and i'll come and look.
Be sure to remember, as you continue to add to this thread that you are complaining about FS using 2% of your cpu...... That's somewhat amusing to me.

Sergey,
that's not a problem, is how FS works.
That load on the CPU when idle is actually not important. Is just the minimum, like in a carburettor.
If you put it under load, you will see that there will need some serious load (many calls) to have it ramp up the cpu usage.

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

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.

I follow this thread, and did top on my Linux Fedora 10 64bits and freeswitch last svn version (without mod_vmd that not compiles anymore) in idle mode and I get 10399 root 20 0 438m 37m 8744 S 11.3 0.5 15:31.61 freeswitch if I remember the previous version took less resources Regards F
