Hi Nicolas, you are right, there is no special function for children destroy. Most modules do not need it, as the data is in shared memory, processes are started over standard kamailio APIs which will be stopped from the core automatically, to give some background. Some modules do it by just iterating over an internal list of their children and then do the cleanup task. You can find an example in cdp module (destroy, diameter_peer_destroy).

Hello, I have a module, for which I need to perform some processing in the children processes when Kamailio is being stopped. I've looked at the "struct module_export", in which I see "mod_init", "child_init", "mod_destroy"... but no "child_destroy". :/ Is there a way to achieve this ? Thanks for your help.
