Hi,
We've recently migrated to a Windows 2016 Failover Cluster with Storage Spaces Direct. Backend is based on an Ocata packstack installation. The cluster has 3 win2016dc node.
So far, everything appears to be working as expected. However, when taking a look at the neutron's log file on one of the node, we're seeing the following errors, literally every 2-3 seconds. The neutron logfile keeps growing:

We have tried to migrate the specific instance who has that port binded to a different node, but the error still shows up on the node where the instance has been migrated to.
I have verified and it doesn't appear to be the same "name" / "id" for the specified resource ("3cef1e9b-9925-4926-83ae-e90d3824fc2b"):
# neutron port-list|grep 3cef1e9b-9925-4926-83ae-e90d3824fc2b

Any ideas what might be wrong ?
Thanks!
