How can I reproduce this? How can I reproduce this? Looks like it was fixed upstream. Changing the external bug to link to the older discussions Should be fixed in all versions of OSP 11. verified for openstack-keystone-11.0.0-0.20170127043446.cefbc3c.el7ost.noarch When using a MariaDB Galera cluster, the error happens due a race condition [1]. To try to reproduce the error, I've run a big concurrency rally scenario test that would create and delete several roles and projects - this triggers several revocation events. No error was reported or found in keystone logs. Marking as verified due the lack of evidence the issue persists rather than an actual validation.
