nginx uwsgi connection timeout

[jpherbst]

Hello,

I have nginx 1.6.1 setup in front of uwsgi 2.0.7 using uwsgi_pass, which has
been working very well for me except for one request.  When I make the
failing request uwsgi processes the request and returns the response in less
than a second, but nginx just sits there with an open connection to uwsgi
eventually timing out after 60 seconds as if uwsgi did not send back a
complete request.  I have many other pages hosted on this server all of
which work just fine, both post and get requests.  The one difference I have
noticed about this request is that the response is very small, 14 bytes of
json.  I have tried using both chunked and not chunked (with content-length
header) encoding, they both yield the same result.  I tried adding
"uwsgi_buffering off;" to my configuration, this allowed the request to
complete, but the next request hangs because nginx doesn't think the
previous request is finished and I only have one uwsgi worker.

Does anyone have any ideas about what could cause this?

Thanks for your time,
Jon
