Broken Pipe Error while running django-test with selenium
Make sure that the browser requesting the page is waiting for the response.
If i remember correctly there is the selenium_client.implicitly_wait(sec) and selenium_client.set_page_load_timeout(sec) commands for that, make sure you are using it.
If not the server will try to write to a pipe that is broken because the browser close the connection before the response was sent.
