Hello,
if you do:
kamctl mi get_statistics all
do you see an increase of active transactions counter?
Would be possible for you to compile with MEMDBG=1 and then get the memory logs?
make MEMDBG=1 cfg
Then add your extra modules in include_modules variable inside modules.lst
Afterwards:
make install
Edit kamailio.cfg and set memlog global parameter to a lower value than debug global parameter.
Run kamailio for a while with the new config, when you see the shared memory keeps increasing, stop kamailio. Send the log messages from syslog to mailing list or made them available for download somewhere.
Cheers, Daniel

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 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

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
