Required Configuration:
-- On the virtual server, the service-down-immediate-action is set to 'reset' or 'drop' and 'connection-limit' to be any (not 0).
-- The pool member has rate-limit enabled.
Required Conditions:
-- Monitor flap, or adding/removing monitor or set the connection limit to be zero or configuration change made with service-down-immediate-action.
-- At that time, one of the above events occur, the pool member's rate-limit is active.

Note: The affected virtual server may automatically recover upon the subsequent monitor flap, etc., if no rate-limit is activated at that time.
