    This looks like the same issue I ran into not long ago. Switch your
    netflow over from full to lose lots of data, but your
    hardware can't handle full netflow for your traffic level.

    AFAIK, your only other options are to mess with the mls aging timers
    (shorten them) or buy cards with DFC and hope that gets you enough
    additional netflow capacity for the interfaces your collecting.
