children parameter is to specify the number of workers per udp socket (or other sockets, a matter of different parameters). It is normal to have more than its value, because kamailio creates also timer processes, etc.

You can do 'kamctl ps' to see the list of processes and a short description of their purpose.

Cheers,
Daniel

I set value to 3. The program can be started,  but number of the process is 8

1. if I set 20, it will start 20 processes
2. if I set 3, it will start 8 processes

I want to know the minimum of process is whether 8. Can I set it to one process ?

/* number of SIP routing processes */

Hello,

what are the error log messages printed in such case? Check your /var/log/syslog or /var/log/messages.
