Apache2 and mod_wsgi: truncated or oversized response headers received from the daemon process

My application works with Apache 2 server using mod_wsgi, Flask and Python 2.7. Oddly enough, the application crashes when the page refreshes. For me, this happens on every update. You can see it here . Also, in Chrome, if I open the web inspector tool, the program will not work.

In the logs I see:

[Tue Apr 14 13:45:29.137444 2015] [wsgi:error] [pid 32713] [client 146.203.54.32:58816] Truncated or oversized response headers received from daemon process 'localhost:80': /etc/g2e/htdocs/g2e

...

FWIW, I use

Linux 3.16.7-7-desktop #1 SMP PREEMPT Wed Dec 17 18:00:44 UTC 2014 (762f27a) x86_64 x86_64 x86_64 GNU/Linux

Any help is appreciated.

I may have a setup. I had this problem, but now it works somehow.

  • mod_wsgi . , .

  • mod_wsgi -,

    python manage.py runmodwsgi --reload-on-changes # for Django

(mod_wsgi 4.4. [1-13], apache2, python 2.7, Django 1.7, Debian8, virtualenv)
