That says that as far as nginx is concerned, its upstream (presumably
a Thin server) took too long before returning useful content. That
suggests a problem on that Thin server, or with the "timeout" values
that nginx and Thin have being different.

That just says that the response was too big to fit in nginx's memory
buffers, and so was written to disk. Not a problem, unless you don't
expect the response to be that big.
