So i have Nginx as a web server with PHP running as fastcgi what nginx serves traffic via upstreams. The strange bug i have encountered is the fact when i upload a large file lets say 2GB and PHP must pass this file to a mapped hard drive via network sharing. PHP/Nginx does not serve traffic to anyone until that temp(uploaded file) has been successfully moved to the mapped hard drive. Does anyone know why it would be locking up like this or how to solve it ? I don’t think it is Nginx i think it is just PHP that is locking up. But it is a nightmare trying to figure out how to keep it serving traffic since there will be 60-120 seconds while PHP is pushing this file to the mapped hard drive that no traffic gets served and everyones pages keep loading (they don’t time out just keep loading / waiting for first byte what is always sent as soon as the file upload is complete.) If it helps its latest php builds default production config and itpp2012’s Nginx Build.

There is a no\_buffer option for proxy you could try (see regular manual for correct function name).

Hi itpp2012 thanks for the swift response :), I am not proxying to PHP Nginx passes the request to the fastcgi upstream Nginx + PHP are both on the same machine just the storage machine (the mapped hard drive) is seperate. I did look in the docs and find this “fastcgi\_buffering off;” And “proxy\_buffering off;” [http://nginx.org/en/docs/http/ngx\_http\_fastcgi\_module.html#fastcgi\_buffering](http://nginx.org/en/docs/http/ngx_http_fastcgi_module.html#fastcgi_buffering) [http://nginx.org/en/docs/http/ngx\_http\_proxy\_module.html#proxy\_buffering](http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_buffering) Is that what you are referring to ? I will give a go with those directives and reply back if it is fixed or not.

Those directives did not fix it. But i decided to investigate sessions and temporary upload directory of PHP. Now the temporary session directory gave me the same no loading issue until uploads have been moved to the mapped hard drive by php. But the following seemed to change that and actualy allow me to keep serving traffic with uploads being pushed to the mapped hard drive. Inside PHP.INI [PATH=C:/server/websites/public\_www] upload\_tmp\_dir=Z:/server/websites/temp-uploads C:/ is the local machine drive where nginx + php is presant. Z:/ is the external mapped hard drive. Now i don’t know why that seems to fix it perhaps someone can elaborate ? Also it comes at a cost it takes twice as long for a upload to be pushed to a mapped hard drive for some reason like that.

Yea thats it, I knew they were there but couldn’t remember them as fast.

Sounds like a blocking disk driver issue, look at the driver settings, dma/pio/caching/advanced sata/etc… Dynamic content is also best served from a different drive (virtual or real) then where nginx is running from.

Thanks for the information 🙂 everything is default though so i am not sure what i should even be changing anything to. On the mapped hard drive “Z:/” it has the settings [![](http://i633.photobucket.com/albums/uu52/C0nw0nk/Untitled9.png) ](http://i633.photobucket.com/albums/uu52/C0nw0nk/Untitled9.png) Posted at Nginx Forum: > **[Re: Nginx + PHP Windows Network Sharing Uploads locking/slow load time](https://forum.nginx.org/read.php?2,260193,260205#msg-260205)** > > So i have Nginx as a web server with PHP running as fastcgi what nginx serves traffic via upstreams.

This is expected behavior if you are using PHP sessions. See [PHP: session\_write\_close - Manual](http://php.net/manual/en/function.session-write-close.php) ---

So its because i’m using PHP’s built in file session handler ? Should i switch it to maybe Wincache or something ?
