When running a python app as WSGI, you need to use maximum 1 thread! Example with apache config: 


   $ grep WSGIDaemonProcess /etc/apache2/sites-available/10-cinder_wsgi.conf
   WSGIDaemonProcess cinder-api display-name=cinder_wsgi group=cinder processes=8 threads=1 user=cinder

This settings needs to be tuned in order to make sure that Nova API will give you an expected number of objects..
