Cause: During a multipart upload, when the upload of a part failed and was restarted, such as due to a time-out, sometimes the cleaning up of the first attempt would remove tail objects from the subsequent attempt. Consequence: The resulting RGW multipart object will be damaged as some tail objects will be missing. It will respond to a HEAD request but fail during a GET request. Fix: The code now cleans up the first attempt correctly. Result: The resulting RGW multipart object is no longer damaged and can be read by clients.
