            Description

            The statemachine handling DCP IdentifyRequest frames is using a timer to answer to received Requests (as defined in Profinet specification). If this timer hits while system is in a heavy load situation it may happen that the timer event gets lost (due to full task queue).

            If this happens the statemachine gets stuck in this state and will never again answer to any DCP IdentifyRequest again (even if the load is completely gone).
