Trying to stop non existing thread about pjproject HOT 3 CLOSED

I have created a patch to fix it in #3901.

One thing worth mentioning is that the app seems to initiate media stoppage by calling MediaLine::stopTransport(). I believe this shouldn't be necessary since typically the media should be stopped by other components, such as the call itself via pjsua_media_channel_deinit().

If the issue still persists, please provide us the stack trace of the two threads that race, i.e. the threads that call pjmedia_transport_media_stop() at the same time.

That seems to fix it, thanks!

We don't use pjsua for our IVR (for performance reasons), we use pjsip and pjmedia directly. Hence why pjsua_media_channel_deinit() isn't called.

Hi,
After some more research of the fix, I saw that pjmedia_clock_stop() is now protected by a mutex only in dtls_media_stop(). But pjmedia_clock_stop() is called from within ssl_flush_wbio() as well without mutex protection, so we could still get the error trying to stop a clock that is already stopped by another thread.
