All those timestamps in the far past and future? Does this look right?
I didn't even show you all the packets, but it is just an example.

Other "problem":
Around 20.00h (19.00 UTC) I had a peak in load (1.10) and about 20 KB/s
traffic. A packet is 76 bytes, so about 270 requests/sec. Do others see this
too?

Please comment.
Thanx,
Jos

BTW: there are good packets too, so I don't think it's my server ;-)
