socket CLOSE_WAIT problem and 404.html

[Oon Arfiandwi]

Hi All,

I have a website that hits by automatic scheduled job every hour from
thousands sources.

last time, my website is down because of thousands CLOSE_WAIT when I check
using "netstat -na"
I already try to debug refer to http://www.ruby-forum.com/topic/204589
but I don't know what to do with the debug log.

when I check the "lsof -p <nginx>":
i found a lots of sockets (CLOSE_WAIT) and file open of my 404.html.
i think there's a problem with my 404 configuration.
