[Freeswitch-dev] uuid_bridge bug?

I am using FS r13096, sometimes uuid_bridge will hangup both legs with no obvious reason( see the debug log below )

The scenario is
1.       Caller(8002) Connects to Callee(7001)
2.       8002 then is parked by using uuid_park ( hence, 7001 is released )
3.       now using a simple lua script ( as listed below ) to re-connect 7001 back to the parked call
4.       most of the time, the re-connect will success, however, sometimes it will drop both legs.


local api = freeswitch.API();

-- Invite the requestor
local ses = freeswitch.Session("user/" .. requestor);
if ses:ready() then
        ses:answer();

        -- Get the UUID of this leg
        local uuid = ses:getVariable("uuid");

        -- Bridge it to the parked id
        freeswitch.consoleLog("info", "uuid_bridge " .. parkedid .. " " .. uuid .. "\n");
        api:execute("uuid_bridge", parkedid .. " " .. uuid );
end
