Thanks for the explanations (both Anthony and Michael).<br>
You both clarified the subject quite well.<br>

the pool before you exit the thread.<br>
<br>
You cannot bring the session with you into the thread unless you read
lock the session first so it will not be destroyed while<br>
you are using it in the thread.<br>
<br>
Be aware keeping the session around in the thread just a wild goose
chase from doing it the why it already was doing it.<br>
The session thread is already independent and it does not stop any
other call from proceeding so you may as well do all the work<br>
in your session thread in the state change handler like it already does
and just add more strict timeout.<br>

(why is it that we always come with the solution right after posting
to
the list?)
I inserted :
thread_params = switch_core_session_alloc(session,
sizeof(*thread_params));
before the pool initialization.
But still, can I get some answers to the questions bellow about
how to effectively handle memory allocations?

when the program reaches the last line (thread_params->session =

I get a core dump. Is this a memory allocation error? Is it because
I am
making
use of the wrong pool? Please enlighten me because I am not an
experienced c
programmer, and I am struggling to get familiar with the FS API.
