apache - Apache2 and mod_wsgi: Truncated or oversized response headers received from daemon process -


my application running apache 2 server using mod_wsgi, flask, , python 2.7. oddly enough, application crashes when page refreshes. me, happens on every other refresh. can see here. furthermore, in chrome, if open web inspector tool, program not crash.

in logs, 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 daemon process 'localhost:80': /etc/g2e/htdocs/g2e [tue apr 14 13:45:29.671493 2015] [core:notice] [pid 28845] ah00052: child pid 640 exit signal segmentation fault (11) [tue apr 14 13:45:29.671520 2015] [wsgi:info] [pid 28845] mod_wsgi (pid=640): process 'localhost:80' has died, deregister , restart it.

fwiw, using

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 appreciated.

i may have tweak. had problem it's working somehow.

  • i tried run mod_wsgi daemon. application didn't work , had error message in logs.
  • however running mod_wsgi non-daemon worked, instance

    python manage.py runmodwsgi --reload-on-changes # django 

    so once again launched killed it.

  • my app still running :)

(mod_wsgi 4.4.[1-13], apache2, python 2.7, django 1.7, debian8 fresh install, or without virtualenv)
