Saw this report just now, but we had the same issue and were caused by slow quantum server. In addition to port created by scheduler retrying request on a different compute, we also have a bug in the quantum client as reported here https://bugs.launchpad.net/neutron/+bug/1267649. We were able to fix this temporarily by increasing the timeout value for the quantum_url_timeout property in nova compute to larger values, 2 minutes in our case.
