I had this exact problem yesterday which, when I restarted the server, seems to have been resolved(I can't see the ERROR message again logged after restarting). You can see the conversation I had about this herehttps://ask.openstack.org/question/1480/compute-usage-meters-from-ceilometer/. See the comments to the answer by Ruslan Kiianchuk.
