Backport #21684
Updated by Anonymous over 6 years ago
https://github.com/ceph/ceph/pull/18138 When 'rgw_keystone_url' is set, and 'rgw_keystone_revocation_interval' or 'rgw_keystone_token_cache_size' are set to 0, the TokenCache revoke thread is not created/started. On RGW shutdown, the TokenCache destructor tries to join this revoke thread and Thread::join triggers an assert.
