[Freeswitch-dev] uuid_bridge kills both channels if they are executing java app

Hi there!

This message is a forward from user-mail-list.
I'm trying to fix such a problem:
FreSwithch compiled from SVN-trunk, date = 11/02/2009.

What is need: connect two users, initially one is on the home-grown
java-based IVR and other party is off hook.

What is done/got:
User1 is on the java application, it represents simple IVR system, and the
most used FS API operation is "streamFile".
User2 is off hook.
next:
(mod_socket) create_uuid
<get uuid_x>
bgapi originate
{origination_caller_id_name=User1}[origination_uuid=uuid_x]User1 &park()
<User1 answers incomming call>
<get event channel_User1 answered>
<get event channel_User1 parked>
uuid_bridge uuid_User1 uuid_User2
<get event channel_User1 hangup, cause=NORMAL_CLEARING>
<get event channel_User2 hangup, cause=*DESTINATION_OUT_OF_ORDER*>
<both channel_User1 and channel_User2 are down>


FS log is here: http://pastebin.freeswitch.org/11380


Thank you much for any help,
Artem

you should be working on SVN trunk if you are doing development, we are so
far forward from 1.0.4 we can't do debugging very easily.

I don't know all of the details of what you are trying to do but you are
hitting some race conditions because of the async nature of the socket
connection and the way you are using it.
