"fatal python error: pyeval_acquirethread null new thread state" in logs of mod_wsgi

[Voland]

I've successfully upgraded to 12.10 release, but after reboot this line appeared in logs of Apache and Django:

Fri Oct 19 13:38:43 2012] [info] mod_wsgi (pid=6911): Shutdown requested 'fantomas'.
[Fri Oct 19 13:38:43 2012] [info] mod_wsgi (pid=6911): Stopping process 'fantomas'.

[Fri Oct 19 13:39:18 2012] [info] mod_wsgi (pid=7135): Create interpreter 'fantomas|'.

So I have 200 error of Apache:

The server encountered an internal error or misconfiguration and was unable to complete your request.

python manage.py runserver

works fine:

voland@django-dev:~/sandbox/fantomas$ python manage.py runserver
Validating models...

0 errors found
Django version 1.4.1, using settings 'fantomas.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

django.wsgi:

import os, sys

sys.path.append('/home/voland/sandbox')
sys.path.append('/home/voland/sandbox/fantomas')
os.environ['DJANGO_SETTINGS_MODULE'] = 'fantomas.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

WSGIScriptAlias / /home/voland/sandbox/fantomas/deploy/django.wsgi

What should I do to get my django back to work?

[dino99]

have you some packages from ppa(s) ? maybe some conflicts

[Voland]

No, there are no packages from ppa.
I've solved problem with server misconfiguration, Django started to work, but I still have this errors in logs

What was the misconfiguration? I've just started to see the

PyEval_AcquireThread: NULL new thread state

error, but only occasionally.
