Hello,
Maybe someone else can correct me if I'm wrong, but I'm not aware of fault-finder being capable of this - it's just for detecting the issues, not preventing them or otherwise interfering with switch operation.
Actually I don't believe there's any way to do what you are asking about. Usually one would just set up monitoring and alerts via SNMP in case of such an event, and then go ahead and fix it when it happens. If you've also got link aggregation in place it shouldn't be such a big issue to have a flapping link either... it would likely be a bigger issue to have a link get shut down because of flapping.
