Hello, I just ask this question for more understanding during developing new module in Kamailio, A you know better than me, we could use register_procs and fork_process functions to create new fork process in Kamailio project. I just did the same things for first handover interface in hiops module. Finally you could see list of all process with "kamctl ps" command. I want to do the same things for third handover interface in hiops module, But i think it would not be nice to see a lot of list of process in output! This conditions would be occurred if someone set the hi3_worker_process parameter in hiops module to 100. Am i right? Don't you think it is better to use nested fork process instead? What do you think? With Best Regards.Mojtaba
