Question

While I was adding content for my django web site on admin panel,I get the error.After I added 10-15 content,site give the this error. “The page you are looking for is temporarily unavailable.“

I analysed nginx and uwsgi logs.

Nginx log contains to below line.

2012/06/02 22:02:53 [error] 5203#0: *602 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 92.10.214.1, server: server.com, request: "POST /admin/hdduyuru/duyurular/add/ HTTP/1.1", upstream: "uwsgi://127.0.0.1:1235", host: "127.0.0.1", referrer: "http://127.0.0.1/admin/hdduyuru/duyurular/add/"

And uwsgi log contains to below line.

invalid request block size: 4169 (max 4096)...skip

I’m using below line to deploy my site on uwsgi+nginx

/usr/bin/uwsgi --socket 127.0.0.1:1245 --master --workers 5 --harakiri 30 --disable-logging --daemonize /tmp/daemonize.log --pidfile /tmp/pidfile.txt --vacuum --gid 500 --uid 500 --ini /home/uwsgi.ini

/home/uwsgi.in

[uwsgi]
chdir=/home/
module=hdblog.wsgi:application
master=True
pidfile=/tmp/project-master.pid
vacuum=True
max-requests=5000
daemonize=/tmp/hdblog.log

Looks like the request headers may have exceeded the default uwsgi maximum buffer size of 4k. Try increasing the buffer size by adding buffer-size=32768 to your uwsgi.ini file.
