Stale channel that cannot be killed, session created from a running Lua scripts.
I have lua 'background' script that wake up every few seconds, and check to perform specific task, one of it to established call. Calls are then initiated then transfer to some extension in dialplan. The scripts has been running and works as expected. But after session ended(hangup), channels is not released and can be seen using cli "show channels". and trying to kill such channel result in "-ERR No Such Channel!" This seems being reported before, but I can't seems to find any resolution. Following simple script could replicate the issues : freeswitch> luarun SimpleDialer.lua =================== SimpleDialer.lua local threadName = "SimpleDialer" while true do freeswitch.consoleLog("info", threadName.." ticking\n") -- task run here local new_session = freeswitch.Session('sofia/gateway/vox/+150<%2B15085895115> 88888888') new_session:transfer("echo", "XML", "default") freeswitch.msleep(60000) end ============= dialplan entry <extension name="echo"> <condition field="destination_number" expression="^echo$"> <action application="echo" data=""/> </condition> </extension>
try new_session:setAutoHangup(0); new_session:destroy(); before you transfer it. and new_session = undefined; after you transfer it. The sessions are tied to the garbage collector so until the script frees the script version of the session the core can't free the real version. the :destroy() method detaches the 2 so the channel can hangup on its own and you only save the shell of the wrapper in your GC.

These scenario only occurs when initial lua script is running forever ( or in loop for period of time ). Initially, I thought calls had been transfer and hangup separately, Lua standard garbage collection ( using local variable on "new_session") will take care of cleaning up the var. So it shouldn't lockup the channels. But, as what been said ============ The sessions are tied to the garbage collector so until the script frees the script version of the session the core can't free the real version. the :destroy() method detaches the 2 so the channel can hangup on its own and you only save the shell of the wrapper in your GC. ============ So, the key is on destroy method. this already documented in wiki, I just wasn't sure what it meant before.
