Rabbit DuplicateMessageError: Found duplicate message in linuxbridge-agent.log

My provisioning has stopped working, and I get VM in ERROR state when trying to nova boot. This is on CentOS7/Liberty release. I can see errors in nova-compute.log that seem to lead to neutron node. Please see paste below. Any advice is appreciated. Will

  • I have tried,

sudo rabbitmqctl set_permissions openstack "." "." ".*" and restarting my services

  • sysctl fs.file-nr; fs.file-nr = 1640 0 512000

  • credentials for connecting to the rabbitmq-server are verified

Here's what linuxbridge-agent.log gives me.
