Public bug reported:

Paste of failure:
http://paste.openstack.org/show/491014/

When looking at the LB agent logs, you start seeing RPC errors as
neutron-server is unable to access the DB. What's happening is that
fullstack times out trying to kill the LB agent and moves on to other
clean ups. It deletes the DB for the test, but the agents and neutron-
server live on, resulting in errors trying to access the DB. The DB
errors are essentially unrelated - The root cause is that the agent
refuses to die for an unknown reason.

The code that tries to stop the agent is AsyncProcess.stop(block=True, signal=9).
Another detail that might be relevant is that the agent lives in a namespace.

** Affects: neutron
     Importance: High
         Status: Confirmed
