Title:
brutal stop of ovs-agent doesn't kill ryu controller
Status in neutron:
Fix Released
Status in tripleo:
Fix Released
Bug description:
It seems like when we kill neutron-ovs-agent and start it again, the
ryu controller fails to start because the previous instance (in
eventlet) is still running.
(... ovs agent is failing to start and is brutally killed)
Trying to start the process 5 minutes later:

I haven't figured out yet how the previous instance of ovs agent was
killed (my theory is that Puppet killed it but I don't have the
killing code yet, I'll update the bug asap).
