[SR-Users] FW: Regd. t_suspend() and t_continue()

[Jason Penton]

Hi,

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.

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.

Secondly, how are you using top to tell that you have a leak? Kamailio's
memory is internally managed.

Cheers
Jason
