My application is a uwsgi+django setup. I use gevent to do performance testing and run 1200 requests concurrently. At this point, uwsgi will throw an IO error with the following log message:

uwsgi_response_write_body_do(): Broken pipe [core/writer.c line 260]
IOError: write error

Django 1.4.0
uwsgi: 1.9.13
python: 2.6
TCP Listen queue: 1000

What is the cause of this broken pipe error?

python django uwsgi
