<p class="xmsonormal">We tested this in dev and qa and then implemented in production and it did make a difference, but 2 weeks later we started seeing an issue, first in dev, and then in qa. In syslog we see neutron-linuxbridge-agent.service stopping and starting[1].
In neutron-linuxbridge-agent.log we see a rootwrap error[2]: “Exception: Failed to spawn rootwrap process.”<o:p></o:p></p>

<p class="xmsonormal">If I comment out ‘root_helper_daemon = "sudo /usr/bin/neutron-rootwrap-daemon /etc/neutron/rootwrap.conf"’ and restart neutron services then the error goes away.<o:p></o:p></p>
