<div dir="ltr">Hi,<div><br></div><div>I have some questions for you as we have used suspend/continue quite a lot in the IMS code and don't have any leaks. </div><div><br></div><div>Firstly, why are you using pkg_mem for your hash_id and label? Remember that you will be in 2 different processes in the suspend and continue portions of the code... so pkg_mem will not work - you should use shm_mem instead.</div>
<div><br></div><div>Secondly, how are you using top to tell that you have a leak? Kamailio's memory is internally managed.</div><div><br></div><div>Cheers</div><div>Jason</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">

We tried t_release() after step (4) to release the transaction as t_relay() anyways allocates new shared memory.
