  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, 

  1)      Do a t_newtran() 

  2)      Allocate pkg memory for hashid and label.

  3)      Call t_suspend() 

  4)      Do t_continue() when async result is
available 

  5)      De-allocate pkg memory reserved for
hashid and label 

  6)      Do a t_relay() which forwards the sip
message to another sip  node.

  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
