TMM is leaking memory related to 'tm_opaque' and 'fw_nat_connflow_opaque' when the BIG-IP system is provisioned with AFM and uses security log profiles in the virtual server.


TMM memory usage increases gradually and system eventually runs out of memory over the period of time.


-- AFM provisioned. -- Security log profiles created and used with the virtual server configuration.



Fix Information

TMM memory usage gets stable and there is no memory leak with 'tm_opaque' and 'fw_nat_connflow_opaque'objects.
