Nginx error

I might find out the problem.

I got some idn doamins. They are running wordpress with wp super cache, when
I request the inner page (the url path is not English, so is the cache
file). Nginx seems can't get the inner page(no problem for front page). Then
nginx become really slow and then stop working. After I deactive the wp
super cache for the idn domains, then no more problem so far.

I think the problem is related to wp super cache or their rewrite rule. It
seems nginx can't find the url and continous request or looking for the idn
cache file, so make the server really slow. I can't remember which 50x page,
since I can't reproduce the problem now.

Thanks for all input, anyway.
