The Neutron API with WSGI module, and specifically when using ML2/OVN, was importing some system libraries before patching them. That was leading to a recursion error, as reported in the related LP bug. By calling ``eventlet_utils.monkey_patch()`` at the very beginning of the WSGI entry point [1], this issue is fixed. [1] WSGI entry point: $ cat /etc/neutron/neutron-api-uwsgi.ini ... module = neutron.wsgi.api:application Closes-Bug: #2075147 Change-Id: If2aa37b2a510a85172da833ca20564810817d246
