Ok :-)

Right, I'm trying.

The thing is: The ISP is a 200Mbps network with 10,000 users. The
first time it took around 2 minutes to trigger the bug. The second
time it took around 17 minutes.

So I *think* it's some TCP flag with some weird content...but I can't
find out what it is so I can trigger it on the lab.

So my only guess is to enable every possible debug flag I can think of
to track the bug down on the production environment. Any hints here
would be appreciated :)

Cheers,

Felipe Damasio
