Greetings,
I have my core parameter listen like this :
listen=udp:eth0
children=12
Like this and the other settings, my kamailio has 21 threads and 20 Sql connections.
If I add more listens,
listen=udp:eth0 listen=udp:eth0:5072 listen=udp:eth0:5074
Now I have 45 threads and 45 Sql connections.
Why does this happen and can i set a a number of threads and/or sql connections that doesn't change with the number of "listen" parameters that i have ?
Best Regards,
Duarte Rocha
Unfortunately, you can't.
Every child worker process has its own database connections, and child worker processes number (children * listeners).
This is actually by design; if database connections were shared among child processes, then in high volume operations, the mutual exclusion ("mutex") locking required for multiple processes to share connections would become a drag on performance. This way, every child process can access the database in its own "lane" without having to fight with any other process over a shared handle.

Assuming you expect less traffic on the alternative ports, you could lower the number of socket workers for those ports. https://www.kamailio.org/wiki/cookbooks/5.1.x/core#socket_workers
