Your example is in bits and doesn't quite apply. I ~think~ the answer to his question is in the 32-bit counter wrap problem. I forget the exact number but at somewhere north of 109 megabits per second, the 32-bit counter will wrap twice within a 5-minute period, giving inacurate results. Try :::::2 at the end of your target string as per the reference.html and see if your gig interfaces support 64-bit counters.
