Are you serving file as static one with nginx, or proxy_pass to
some backend server? In later case most likely reason is out of
space (or no access to) in proxy_temp_path.

Please make sure you have error_log properly configured and you
are looking at right one. Most simple aproach is to configure one
at global level and remove others if any (i.e. at http, server,
etc. levels), e.g.

error_log /path/to/error.log info;

Note that setting logging level to 'info' may be important in some
cases (e.g. if nginx thinks client timed out or so on).

If the above wouldn't be enough to solve you problem, please
follow generic instructions as outlined at
http://wiki.nginx.org/Debugging, i.e. please provide

1. nginx -V output
2. full nginx config
3. debug log
