ovs_neutron_agent out of sync with plugin, agent tunnel out of sync with plugin
I'm deploying openstack icehouse version with three-node architecture (controller node, network node, and compute node1) on Debian wheezy.I use ml2 plugin and gre type driver.
Now, I notice some exceptions information in both the ovs-agent.log of network node and compute node.

From http://openstack.redhat.com/forum/dis... , & https://lists.launchpad.net/openstack... . the first link prompts to add tcp connection in iptables, but I disable firewall rules. So this does not work.
Also, I refer as to source code of neutron ( https://github.com/openstack/neutron/... ), but have no idea.
I just want to understand why this information exists and then eliminate the information. Thanks in advance.
