 (fwd)

Hi Daniel,

I forward part of the details to public knowledge (and for Thomas mainly).

I also put the epoll & accept only log available for him at
http://www.cs.helsinki.fi/u/ijjarvin/tcp/epoll_accept.txt
as it won't contain encryption key, etc. related bits.

Can you Daniel please confirm what exactly was the status about the effect 
of disabling ntpd?

	Hi Ilpo, so we can hurry up this debug, I'm sending before,
during and after the stall, just to you:

	Obs.: the stall happened at +- 13:06:47... you'll notice lots of epoll_wait.

	The nmap was done at +- 13:07:15.

	Thanks again! :)
