Bug Description

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:\

Hi MSA

Thanks for taking the time to report this bug in Ubuntu; Its possible that this bug has already been fixed either in an SRU or in a later Ubuntu release (Icehouse on 14.04 for example).

Please could you re-test and see if this is still a problem for you; if so please can you run apport-collect 1314276 so that this bug report gets populated with relevant system information.

Thanks!
