How are you configuring the location of the Python EGG cache. Are you using:
1. WSGIPythonEggs directive? Which means you MUST be using embedded mode. 2. Setting python-eggs option to WSGIDaemonProcess? Which means you MUST be using daemon mode and application must be properly delegated to that daemon mode process. 3. Setting PYTHON_EGG_CACHE in os.environ in WSGI script file? 4. Some other way? You need to provide more information about your configuration. Right now, you aren't using the correct way of setting Python egg cache for how you are running your application.
