.Object leaking can occur after using `radosgw-admin bucket rm --purge-objects`
In the Ceph Object Gateway, the `radosgw-admin bucket rm --purge-objects` command is supposed to remove all object from a bucket. However, in some cases, some of the objects are left in the bucket. This is caused by the `RGWRados::gc_aio_operate()` operation abandoning on shutdown. To work around this problem, remove the objects by using the `rados rm` command.
