Hi Daniel,
So in my case :
* Server vcpus = 24
* Max_worker_processes in postgres = 24
* Max_parallel_workers in postgres = 24
* Children in Kamailio config = 12
* 1 udp listener
I noticed that there is 48 database connections established by Kamailio (16 x
3) , can this cause an issue knowing that maximum worker processes is 24 ?
Regards,
Ali Taher

Hello,
in this case there are 3 distinct connections per process, so you have to
multiply the number of processes by 3 to get the overall number of connections.
You can run 'kamctl ps' to see all the processes of a kamailio instance.
Actually a few kamailio processes may not open database connections, a matter
of their purpose if they are created by specific modules, but for a rough upper
limit, this is the formula.
Cheers,
Daniel

Hi Daniel,
I meant that I'm defining 3 connection strings using sqlcon parameter of sqlops
module as shown below:
modparam("sqlops","sqlcon","cb=>postgres://postgres:kamailio@localhost:5432/cataleya")
modparam("sqlops","sqlcon","mi=>postgres://postgres:kamailio@localhost:5432/cataleya_mitto")
modparam("sqlops","sqlcon","sp=>postgres://postgres:kamailio@localhost:5432/cataleya_spactron")

hello,
what do you mean by "3 connection strings"? Maybe you can give similar example
here.
Cheers,
Daniel

Thanks for your answer.
Please note that I have set 3 connection strings in SQLOPS module for 3
Postgres databases. How many connections per database does Kamailio open?
(knowing that children=12 and only one listening interface).

Subject: Re: [SR-Users] worker processes
Hello,
note that other processes are created by kamailio, not only sip worker
processes. For example, there will be timer processes.
The dedicated worker processes are only for UDP sockets, not for tcp/tls (here
is a single pool of workers for all tcp/tls sockets). If you do not receive
traffic on a specific udp socket, then do not listen to it, you have a group of
processes not doing anything. If you need to listen on a socket, but have less
traffic (e.g., used for monitoring), then use workers parameter before listen,
so you get less worker processes for that udp socket.
Cheers,
Daniel

Hi,
I just want to ask regarding the children number and listening interfaces set
in Kamailio configuration.
I am given to understand that the total number of worker processes there will
be (children_setting * listeners) , so assuming I have set children=12 and
listen=udp:172.16.1.12:5060 (which is the interface IP where the SIP packets as
received), in this case there will be 12 worker processes and 12 database
connections to postgresql (I'm using SQLOPS).
My question is if I set listen=udp:0.0.0.0:5060 , knowing that I have 3
interfaces, in this case the number of worker processes will be 36. Is this
good configuration ? will the other 24 processes be used or they are reserved
to the 2 other interfaces which are not receiving any SIP packets and then will
be useless ?
