Hello,
it might be due to dialog timeout checking. Do you get many calls
terminated via dialog BYEs? You have some log messages that are printed
for each BYE, that could be slowing the processing -- are these messages
printed by that pid?
Cheers,
Daniel

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.
Regards,
Ricardo.-

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

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?
