.The Ceph Object Gateway retry logic can cause high-CPU utilization
A bug in the Ceph Object Gateway retry logic can cause a non-terminating condition in operations processing, which can lead to high-CPU utilization and less noticeable side effects. This high CPU utilization triggered a "busy-loop" in various workloads. In this update, the error-handling logic has been fixed to handle this condition.
