Handling nginx's too many open files even I have the correct ulimit

I'm facing the same problem here, but I found much lower settings on our
machine (a VPS running Ubuntu 12.04):

# the hard limit of open files
www-data at 215247:~$ ulimit -Hn
# the soft limit of open files
www-data at 215247:~$ ulimit -Sn
# maximum number of file descriptors enforced on a kernel level
# for more info see: http://serverfault.com/q/122679/88043
root at 215247:~# cat /proc/sys/fs/file-max

So I would hope that setting the ulimit values for max open files per user
to 262144 (H) and 131072 (S) will help.

But then again, Howard Chen mentioned, that he's facing this problem despite
such high values on his system.

Any suggestions?
