It seems enabling the following command resolves my problem: <param name="threaded-system-exec" value="true"/> Can anyone explain in detail what this variable does? Thanks! On Mon, 3 Sep 2018 at 20:30, Lee Vidor via FreeSWITCH-users < freeswitch-users@lists.freeswitch.org> wrote:

I'm currently using mod_tts_commandline with a python script to AWS text to speech API. The flow works fine during a single call.
Event socket API -> Freeswitch dialplan -> mod_tts_commandline -> Python script -> AWS API -> Voice file -> Freeswitch say
However when there a number of concurrent calls (even just 10 to 15) the request to execute the python script hangs until all the calls are at the same requesting state. As if mod_tts_commandline is waiting for something to happen.
Dial plan:
<extension name="tts_google"> <condition field="destination_number" expression="^11111$"> <action application="set" data="call_timeout=60" /> <action application="answer"/> <action application="detect_silence" data="100 30 25000"/> <action application="speak" data="tts_commandline|${lang}|${text}" /> <action application="hangup"/> </condition> </extension>
tts_commandline.conf:
<param name="command" value="/usr/bin/python /usr/local/freeswitch/scripts/synthesize_text.py --language=${voice} --filename=${file} --text=${text}"/> </settings>
Execution of python script in freeswitch logs:

The python script executes fine and returns to freeswitch:

Any help or further debugging steps would be appreciated.
Thanks
Lee
