Hello, I am using nginx on an ARM processor based server. In one usage, it is acting as a reverse proxy. In the nginx/error.log I see entries that look like:

an upstream response is buffered to a temporary file /var/spool/nginx/proxy_temp/2/04/0000000042 while reading upstream, client: 127.0.0.1, server: _, request: "....

But if I run the command, "find /var/spool/nginx/ -type f" while the download is ongoing, no file is found. Also if I try to specifically list the file.. nothing is there, but the parent directory....

The user nginx is running as has full access to that directory. Any way to further debug why these files are not getting created ?

# find /var/spool/nginx/proxy_temp/2 -ls
