Yes, the restart of tmm DOES clear the leaked memory. However it's an outage for that unit, which is probably why it's not listed as a 'workaround' :) [The restart is exactly what causes an outage when it restarts itself. You'll see an error in the tmm log when this happens and alarms go off, services failover, tmm restarts and we do the whole thing again]

 

FWIW I had the same issues in 11.2.1HF6 (Although it wasn't identified as a leak due to SNAT, it was a leak. The TMM would restart after about 4 days, so the temporary work-around until we dropped the ENG HF on the units was to schedule a tmm restart overnight on a rotating basis).
