[Freeswitch-dev] Freeswitch crash using mod_event_socket

[Georgi Stefanov]

 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.

Does anybody have any ideas?
Am I making something wrong or it is bug in FS ?
