Well that is why I asked, I assume there is some relation between the
"accuracy" of the digest and how many hits you get on neighbour caches?

I seem to get rather a lot of UDP_MISS requests in my logs.

Unfortunately I did not notice (until you asked) that my log scripts stopped
rolling over correctly when I upgraded to 2.4S2 3 weeks ago - so I don't
have accurate summaries at the moment.

Now that is corrected, I will get some more over the weekend, so I will be
able to answer your question more accurately
