Got love nanog..
A nice man from cisco called me, it looked like a lot of packets on my
router were being process switched (sh ip cache - displayed A LOT of
entries). Anyway, it turns our some of my atm sub-ints inherited a "no ip
route-cache cef" from a parent int and well you can see what happens when
the packet volume increase.
Richard I would check that..
So now to life the rate-limit and see what happens..
