This means lockutils.synchronized_with_prefix('nova-') isn't working as expected. While https://review.openstack.org/#/c/119586/ is a possible culprit for this issue, a spot check of nova-compute logs from before that patch was merged show this was happening before (although in my spot checking it happened significantly less often, but I only checked one file).
