    Yes, I have experienced this problem myself. It took me ages to track
    down because the router had about twenty interfaces and I didn't have
    them all listed in the CFLOWD config file. It turned out the be a cut
    and paste between windows that had truncated a couple of IP addresses
    off the end! As it turns out, those were the IP addresses the router
    was using. After that I changed all my configs so that I only used
    the loopback address in the CFLOWD configs and specified the loopback
    as the interface all exports should originate from on the router.

    Same Symptom as what Halldor is seeing, but I'm not sure it's the same
    cause this time...
