Symptoms

The BIG-IP system does not answer the request matching the L7 policy that disabled DOSL7 when BADOS is configured. The connection hangs.

Impact

Connection hangs.

Conditions

Workaround

There is no workaround other than disabling the Behavioral & Stress-based (D)DoS Detection from the DoS profile.

Fix Information

The system now correctly handles a disabled DOSL7 policy.
