Hello,
if you try to use proxy_cache or fastcgi_cache you got this error in error.log of nginx :

You can't disable nginx_push_module, to make nginx cache to work.
Everything is fine if you use the "daemon off;" option.

I've seen this issue in many forum/mailing list, i think
nginx_push_module shouldn't be in the extras package anymore.
