    Attachment: screenlog-2016-11-01.tgz

Hi Richard,

The patches supplied didn't apply cleanly so I updated to the current origin/13 branch which appears to already have the jira_asterisk_26344_v13_committed_fix.patch. The other patches then applied cleanly.

Leaving res_pjsip_output_registration.c with:

{noformat}
schedule_registration(state->client_state, 3 + 1);
{noformat}

gives me a system that still appears to be leaking memory.

mmlog simply has:

{noformat}
1478001617 - New session
{noformat}

But grepping CLI output after running "memory show summary" & "memory show allocations" occassionally through the test run gives me:

{noformat}
grep -e "bytes in all allocations and deferred free allocations" -e "allocations in file.*pool_policy_malloc.c" ~/screenlog.0

  13650533 bytes in all allocations and deferred free allocations
   6791616 bytes in        811 allocations in file ../src/pj/pool_policy_malloc.c
  13670895 bytes in all allocations and deferred free allocations
  13716032 bytes in all allocations and deferred free allocations
  13673257 bytes in all allocations and deferred free allocations
  13698627 bytes in all allocations and deferred free allocations
   6853056 bytes in        871 allocations in file ../src/pj/pool_policy_malloc.c
  13726484 bytes in all allocations and deferred free allocations
  13720457 bytes in all allocations and deferred free allocations
   6991296 bytes in       1006 allocations in file ../src/pj/pool_policy_malloc.c
  13851289 bytes in all allocations and deferred free allocations
  13851545 bytes in all allocations and deferred free allocations
  13934849 bytes in all allocations and deferred free allocations
  13933169 bytes in all allocations and deferred free allocations
{noformat}
I highlighted the pool_policy_malloc.c above as this seems to be the file that shows a steady increase in usage.

I've attached the CLI output as screenlog-2016-11-01.tgz
