Seems that the “Slow timer” is taking too much CPU. Is this normal?. I’m
managing all the calls coming through the server with the dialog module
(dlg_manage ), as I mention I have a rate of 30cps and sometimes I have
4500 active calls….
Could be some way to release some of the CPU use by this process?
Thanks again.

Ricardo.-

Hello,
what is the type of the process? Run 'kamctl ps' and see the description
for that pid.
Cheers,
Daniel

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?

Ricardo Martinez-.
