I didn't resolve this yet.
However, I suspect it's caused by ovs of openstack.
I plan to try again.

Hello mate;)Did you solve this issue? I have pretty much the same problem. I noticed that when I restart origin-node.service it helps. But the problem is occuring frequently. Sometimes to solve it I have to restart whole docker engine.
I've try to debug this issue, nothing found. The common issues are also the DNS resolving problem. Some times, pods cannot resolve the svc names.
