Mike, thanks that raise this problem. I saw the same thing in my devstack. And I solved it by restarting ceilometer-alarm-evaluator service, but it come back after some time and I have not any idea what is the reason.
Also I got it before creating fix for https://bugs.launchpad.net/keystone/+bug/1364463. So I think it's unrelated problem.
