Are you sure you didn't forget/misspell/whatever the WithPeak option ?

In a 5-minute interval you reach a value of 1000K. When you look at the
30-minute interval, this is 6 times longer. This means that your
***average*** is 6 times smaller. 1000/6 is remarkably close to 160...

Try two things:

- Search your log for the 1000K value. If it's there (around line 650 or so)
  but only in the 4th or 5th column: bingo, see above.
- Try to use your old config files and/or compare them with your new ones.

Be aware of global targets such as "WithPeak[^]: ymw" being in effect,
the order is important, they should come before your real targets.

Alex
