The problem was a bit different, some download manager was making
hundread connection to download a 3mb file, this dos-ed the server
for the other request,
we have the plan to move the site to another server, but since
this server should host other sites that needs to be moved,
the operation it's not trivial, we have to schedule the switch
I hope it will be done in this week.
I would also say thanks to guy that offered me a place to host
my stuff

I've attached the patch to this post.

Bye
