<tt>Hello Jorge,<br>
<br>
My bad, I just noticed you query for free mem, not for used mem
:). So you say you are reporting a kind of leak ?<br>
<br>
Have you looked into : <a class="moz-txt-link-freetext" href="http://www.opensips.org/Resources/DocsTsMem">http://www.opensips.org/Resources/DocsTsMem</a>
?<br>
<br>
Try to compile in the mem debugger and make a mem dump before and
after the call -> by diff'ing you will see if there is an
actual leak or not.<br>
<br>
Sometime, the free mem may decrease not because of leaks, but
because of memory fragmentation (more mem fragments are in memory,
so more mem is used for internal management).<br>
I suggest to try to correlate with real_used_size (how much is
actually used, without overhead).<br>
<br>
Regards,<br>

<br>
<tt>Your testing is not really correct as it is not accurate
- it is illogic for memory to drop after the call :).</tt><br>
<br>
<tt>SHM mem is used by other components of OpenSIPS, like
registration, dialogs, etc - so if you really want to
test, you need to be sure your OpenSIPS is (1) actively
doing only b2b and (2) the start/stop sample are before
and long after the call ended (to ensure that all data
expired).</tt><br>
