Persistent connections with HTTP requests that may switch according to dynamic change of DoS policy (using iRule or L7Policy) can cause a TMM crash.
In few scenarios, when DoS policy is changed during connection lifetime, TMM might crash.
A request arrives to BIG-IP and is waiting to be served (it is delayed using iRule), however, if the DoS profile is unbound during that time from the virtual server and a dynamic DoS profile change decision is made, it could potentially cause the request to be incorrectly associated with a context that has already been freed.
No TMM crash due to persistent connections.
