I was checking my recent error logs and found these warning entries.

2009/11/04 15:31:11 [warn] 8884#0: *262 an upstream response is buffered to
> a temporary file /usr/local/nginx/fastcgi_temp/9/00/0000000009 while reading
> upstream, client: EDITED OUT, server: EDITED OUT, request: "GET
> /coaster/download/398/sabertooth HTTP/1.1", upstream: "fastcgi://
>", host: "EDITED OUT", referrer: "http://EDITED OUT/"

My website serves files from the range of 1Mb to those around the 20Mb mark.
The files are served via PHP and presented to the client. Everything works
as it should on the site, but should I be worried about the log entry seen
above? I would prefer not to ignore it.
