TMM cores


Traffic disrupted while tmm restarts.


When using custom iRule actions in a PEM policy, triggering a use of the action or modifying the action will cause the TMM to reset.


Avoid using custom iRule actions in PEM policies.

Freeing of memory for storing the custom action was done to a different pool than whence it was allocated; used the correct free routine.
