I have just done the N -> O upgrade and have seen this error. We have done the expand and migrate db syncs.
We have 3 newton keystones and when I added an ocata one I saw this issue on the ocata one. Its happening on a POST to /v3/auth/tokens and is affecting about 3% of requests (we have around 10 requests per second on our keystone) Happy to provide more information. Currently I have rolled back but am thinking this might just be an issue during the transition so could bite the bullet and do it quickly. ** Changed in: keystone Status: Expired => New -- You received this bug notification because you are a member of Yahoo!

I have 3 controller nodes running behind a HAProxy. Everytime, when I upgraded one of the keystone and bring it back to the cluster, it would encounter this error [2] when I tried to update a created user for about 5 minutes. After I brought back all the 3 upgraded keystone nodes, and 5 or more minutes later, this error will disappear and everything works fine. I am using the same conf file for both releases as shown in [3].
