502 Bad Gateway- NGiNX / uWSGI / Django

[pnovotnak]

I see lots of the following in my logs, and get complaints from users of the website when working in the site's Django admin:

recv() failed (104: Connection reset by peer) while reading response header from upstream, client

I've tried lots of things, and actually found a descriptor leak in the codebase, but nothing so far has helped. I've just applied a buffer size increase, and I'll report back if it solves he issue.

It's a large site, and there are a lot of third party modules that set cookies. I count 24 of them, if that makes a difference.

Maybe try the mailing list or IRC instead? Pretty sure this is not a bug in uwsgi.

Setting buffer-size = 65535 solved this for us.

@pnovotnak In which file to set this. can you tell?

because the default buffer-size is 4k, buffer-size = 65535 solved for me too
