Remarks
A response which cannot be processed does not state the subscription of its message, so this event occurs for it with no Subscription. The session requests the message again from the server until the server no longer holds it; once it fails again, the failure is reported with its subscription, once for each message however often it fails, and once more with BadMessageNotAvailable when the message is lost. Such a failure only occurs here if it is not handled by the NotificationFailed handler of the OpcSubscription.
