Django: WSGI delays

I've deployed a django-application, which basically works fine. The only problem I have is that there are sometimes requests hanging, and I can't find the reason for this. "Hanging" means, e.g. if I click on a link in the admin backend, the browser loads (and the apache access log does not even show a GET-request at this time), but gets no answer. Only if I request again, it gets answered.

I tried out many different WSGI-Configurations, including Daemon/embedded mode changes, changes in the amount of processes and threads etc. I just don't have an idea where to search further. Here my current apache configuation:


    Alias /media/ /opt/myserver/static_media/admin/
    Alias /favicon.ico /opt/myserver/static_media/img/favicon.ico

    WSGIScriptAlias / /opt/myserver/myproject.wsgi
    WSGIDaemonProcess user=www-data group=www-data processes=2 threads=15
    ErrorLog /var/log/apache2/myserver-error.log
    CustomLog /var/log/apache2/myserver.log common


And my wsgi-file:

import os, sys

os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

import django.core.handlers.wsgi

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

Any ideas?


Please check the Apache error logs. There might be a python error/stacktrace in there.

I also think you miss the assignment of the daemon to a hosted folder:

<Directory /opt/myserver/>
    Order deny,allow
    Allow from all
