<p>neutron agent not able to fetch details from ovsdb . Could you check below options 1.restart ovsdb-server and execute ovs_vsctl list-br 2. execute ovs- vsctl list-br manually and try to check error.<o:p></o:p></p>
<p>3. Could be ovs cleanup issue , please check the output of sudo service openvswitch restart and /etc/init.d/openvswich** restart , both should be same
