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?
