Severity: 2-Critical


VPN clients experience packet loss/disconnection.


Connections start to drop as tmm runs out of memory. TMM will eventually run out of memory and connections could be terminated. Traffic disrupted while tmm restarts.


In certain scenarios, the tunnel establishment procedure might leak a small memory. If the tmm is running for a longer duration, this small leak can accumulate and result in out-of-memory condition


There is no workaround at this time.

Fix Information

A rare memory leak during APM VPN establishment has been corrected.
