It's the dupe-mechanism!
It works like this: 

A block is submitted, first it is looked up in the dupe-history
queue. If it is found there, it's a triple dupe. Just increment the
dupe-number (so it says: "block xx, 3 dupes" in the logs)

If it's not found in the dupe-history, look it up in the
"block-history" (explained later). If so, it a double dupe, log it as
"block xx, 2 dupes". Remove it from the block-history-queue en put it
in the dupe-history-queue.

If it's not found in the block-history, it's not a dupe. Add it to
the "block-history", so we can compare subsequent blocks to it.

Oops, typo. I just copied that "rc564-dupe" line from the "rc564-in"
line. It should read: 
"limits adjusted to block-his 117, dupe-his 58"

These numbers are calculated from the inbuffer-figures. You can see
that piece of code on http://ivo.nu/~dcti/tresholds.txt

Integer....

I'll look into it.
