Public bug reported:
A single instance deployment works great but with multiple instance
deployment , I am getting neutron ResourceClosedError and some time DB
timeout and locking error. I am using default neutron version 2.3.0
(havana) in ubuntu 13.10 server with Floodlight (bigswitch restproxy
plugin). Here is the log for neutron-server:\
