Agent out of sync with plugin!

错误：
2015-12-31 19:12:55.321 7618 INFO neutron.plugins.openvswitch.agent.ovs_neutron_agent [req-c3d07c48-e891-4d1c-bfaf-ac2c6227968a None] Agent out of sync with plugin!

这个不是错误信息的
[mw_shl_code=bash,true]  if self.enable_tunneling and tunnel_sync:
                LOG.info(_("Agent tunnel out of sync with plugin!"))[/mw_shl_code]
这是源码分析
