Hi,

 

We are experiencing weird behaviour when using socket connection to mod_event_socket while running FS on FreeBSD and Mac OSX.

 

We send a lot of bgapi and api commands to the FreeSwitch while controlling and monitoring hundreds of sessions.

 

We have created a simple load-test that displays the problem we face.

The load-test simply fires the following command continuosly to freeswitch: “bgapi sofia status”, generally as fast as freeswitch can receive it.

 

The following occurs, but only on FreeBSD or MacOSX (10.6.6) (both 64-bit) while using latest version of FreeSwitch:

 

- Replies and events are inter-mixed on the receive stream (the output from freeswitch), causing protocol errors in the receiving client.

 

This does _not_ happen on CentOS or Windows, so we wonder what could be causing this. Is there a problem with threading or socket libs here?

We assume that FreeSwitch protect a mod_event_socket inbound connection output stream by locking (or other means) to make sure not any two messages are written ‘simultaneously’ causing garbage in the receiving end?
