Okay, so based on your update to the title, and the idle timeout setting (threadpool_idle_timeout).  

If one were to go about fixing this issue.  It sounds like there's one or more threads that are idle, but are not ending.  Are they really idle?  Maybe they were marked idle incorrectly and are still doing something?

Probably more logging needs to be added to resolve this?  There's only information regarding idle threads and destroying them. We don't have startups and pending waits.  It doesn't seem obvious which thread is being waited on that's blocking pjsip (maybe DEBUG_THREADS?)

I'll do some poking here.

P.S.  Also... should it really block on waiting for an idle thread for doing something as critical as responding and sending PJSIP traffic?  Is there a drawback to just allocating a new thread when needed?  I suppose it could run into hitting max threads, but then... at some point eventually the truly idle threads will end?
