We use it heavily, but not using the async module - we use it directly from the IMS code.
Can you please provide your config (or a relevant snippet) file so I can see what exactly you are testing/trying to do

Hi,
Anyone who had used t_suspend() and t_continue() can share the performance details?
I tried async module with one sec sleep time. I tried only 5 calls per second but still it was not successful. After sometime I see below logs,
Jan 21 13:51:55 PLT-RA-RD-W167A PCscf[16520]: ERROR: tm [t_suspend.c:128]: t_continue(): ERROR: t_continue: transaction not found
Jan 21 13:52:49 PLT-RA-RD-W167A last message repeated 15 times

Jan 21 14:13:03 PLT-RA-RD-W167A last message repeated 5 times
Any configuration changes can help here?

Hi Shankar,
What version of Kamailio are you running? Kamailio -V
Cheers

Hi Jason,
Please find below my response inline,
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.
[Shankar] We use pkg_mem because we are invoking t_continue from the same process ( using thread ).
Secondly, how are you using top to tell that you have a leak? Kamailio's memory is internally managed.
[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.
Cheers
Jason

Hi,
We are trying out the t_suspend() and t_continue() in our test setup.
We are facing memory leak ( both shm and pkg as per top command results).
Please find below the scenario,
Do a t_newtran()
Allocate pkg memory for hashid and label.
Call t_suspend()
Do t_continue() when async result is available
De-allocate pkg memory reserved for hashid and label
Do a t_relay() which forwards the sip message to another sipnode.
In the step (6) above, we see t_newtran() allocates one more time
shared memory for the same transaction.
We tried t_release() after step (4) to release the transaction as
t_relay() anyways allocates new shared memory. Nothing helped.
Please let me know what are the logs you would require to debug the same.
I am attaching syslog for this run.
Regards,
Shankar
