Symptoms

TMM leaks memory and eventually crashes when it cannot allocate any more memory.

Impact

Over a period of time, TMM crashes, as it is unable to allocate any more memory. Traffic is disrupted while tmm restarts.

Conditions

OAuth agent is used in APM per-request policy subroutine and authentication fails.

Workaround

None.

Fix Information

When fixed, TMM works as expected and no longer leaks memory.
