Help: Nginx provide blank content.

[tonyy]

I have set nginx to cache files. But sometimes,  we get blank content. I find below message in the logs:

cache file: "/cache/6/cc/5fa7f740d0cf7c2e33cb6c87bb92fcc6"

But this file actually does not exist.

Is this becuase nginx found index in the key zone by the  cache key, but the cache file does not exist (expires?)

How to to solve the problem?
