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}

  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].
