I have tried out RDO with CentOS 6.5 following [1]. I am getting an openvswitch issue, it keep adding and deleting br-tun. my /var/log/message hitting continues message of following. Is any one com across this issue?

And note, I had working setup with multi node (10 days ago), but suddenly with an yum update and re-run packstack lead to this issue. Now even allinone setup also getting this issue.
