   This is because the Nginx upstream module default has a non-zero temp file size configuration:
   
   > 
   >
   > Syntax:	proxy_max_temp_file_size size;
   > Default:	
   > proxy_max_temp_file_size 1024m;
   > Context:	http, server, location
   > When buffering of responses from the proxied server is enabled, and the whole response does not fit into the buffers set by
   the proxy_buffer_size and proxy_buffers directives, a part of the response can be saved to a temporary file. This directive sets the maximum size of the temporary file. The size of data written to the temporary file at a time is set by the 
   > proxy_temp_file_write_size directive.
   > The zero value disables buffering of responses to temporary files.
   
   So when the request is out of in-memory buf, data will be saved into files.
   
   Don't worry it's not a problem.
