I use nginx for reverse proxy on front of apache2. I get a lot of crit  
messages in logs like this.

Hi,

That error is because /webhost/tmp/0004372283 is a file but  
/webhost/tmp/xxxxxxx/ is a directory which is being tried to rename.

I wonder what is trying to rename a file to directory ?

You are configured proxy\_store to /webhost/tmp/. And you have  
other files in this directory, at least nginx’s own proxy\_temp  
and/or other files already saved by previous proxy\_store requests  
(which is likely to cause conflicts due to your site structure).

Additionally, you are trying to save directory index accesses  
without mapping them to files via custom proxy\_store strings.  
This will not work (though will cause different error).

And, after all, you don’t use proxy\_store results at all.

Let me guess: you don’t need proxy\_store at all, right?

Thank you maxim

I also want to store files, I just change server conf /webhost/tmp/xxxx  
and there is no error message at all.

hello

early decision, my image server crit error gone but my app server error  
stil exist. I think the problem is my app server not use .html .htm like  
web page structure. /backup/tmp/0000000844 files are not appear any more  
but error in logs still exist.
