[SR-Users] Question about CPU

[Ricardo Martinez]

Hello.

Is normal this output from the “top” command?!

I have a kamailio with 16 children receiving calls at rate of 30cps and
using the dialog module to timeout the calls :



This is the top command :

The question is : I always see the process PID : 2566 using more CPU than
the rest of the childrens.

Is this normal?
