I must say I'm not surprised. We basically *know* (*) this is because the 
clients are DOSing the server at the same time, so why be surprised if this 
comes back, when the code, which prevented this (poorly), was remmoved?

(*) I forgot why we knew this, maybe its in this bug log even, but there was a 
very plausible explanation, like >500 machines submitting per hour, all at 
the full hour, and the apache config allows 500 connections. Something like 
this.

The solution definitly involves making the clients submit their data at random 
time.

I suggest not to wait 20 days to take action. popcon-stats are widely used, 
and currently people think debian has way less (popcon) users, because our 
popcon system is broken.
