When does Freeswitch starts to fork processes?
Hello, I am trying to chase a problem hapenning from time to time. The problem is that freeswitch starts acting slowly, it starts forking processes and I have to restart it. It did not happen with 1.0.x, but it happens with various 1.2.x; it happened today a few times on 1.2.23 so I reverted to 1.2.22 to see whether it helps in the meantime. Using GCORE on one of the new processes I've found that at least one of them is hung in system() call used by voicemail to email voicemail messages. If I kill the process then the Email is sent. So, when does Freeswitch decides to fork processes and what can cuase system() to hang? I do not open JIRA yet as I cannot jump to the git HEAD (production system and have to do things very carefully... Thanks, __Yehavi:

That's going to be rather dependant on your use-case. For ordinary call bridging it has no need to. You could grep the source code to find out. It'll need to any time you run an external process, such as when sending email (I assume it's wrapping sendmail or similar?). what can cuase system() to hang? Since system() doesn't return until the child process is completed, anything causing that child process to hang would. On 3 April 2014 09:43, Yehavi Bourvine <yehavi.bourvine@gmail.com> wrote:

Check the status of the child process if you gcore or strace it. On 4 April 2014 13:50, Steven Ayre <steveayre@gmail.com> wrote:

I think its just doing this when its calling system commands. Maybe post recording or voicemail for email stuff?
