<p>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.<u></u><u></u></p>
<p><u></u> <u></u></p></div><p><span style="background:yellow">[Shankar] We use pkg_mem because we are invoking t_continue from the same process ( using thread ).</span><u></u><u></u></p><div class="im"><p><u></u> <u></u></p>
<p>Secondly, how are you using top to tell that you have a leak? Kamailio's memory is internally managed.<u></u><u></u></p><p><u></u> <u></u></p></div><p><span style="background:yellow">[Shankar] After running for say 20minutes, we get out of shared memory error. Also in top output we observed incremental increase in the shared usage of shared memory for the process.</span><u></u><u></u></p>
