This is basically the same as described in https://bugzilla.redhat.com/show_bug.cgi?id=1381721. As a fix for that, we did the following changes that are included in latest builds: Set concurrency to 1 for auditor/replicator/updater - https://review.openstack.org/#/c/383724/ Throttle update_auditor_status calls - https://review.openstack.org/#/c/383707/ Closing this bug as duplicate therefore. *** This bug has been marked as a duplicate of bug 1381721 ***
