Tmm crash when using iRule to reject connections when Behavioral DoS is enabled.
With heavy traffic, the tmm process might crash. Traffic disrupted while tmm restarts.
This can occur due to an interaction between a Behavioral DoS policy and an iRule designed to potentially drop some of the connections.
Do not use iRules to reject connections that are bound to a virtual server with a Behavioral DoS policy attached.
Fixed a tmm crash related to iRules and Behavioral DoS policies.
