Hello All, Recently I have played with mod_event_socket on Freeswitch. I have noticed that when I try to make fast calls 100 calls per second Freeswitch makes core files. When I do not use mod_event_socket, but I use IVR capabilities of FS I have no core files and event I have succeeded to make 150 calls per second Here is some backtrace extract. The interesting thing is that FS crashes on different code every time.
