Unless otherwise stated in the notice of dismissal or stipulation, the dismissal is without prejudice, except that a notice of dismissal operates as an adjudication upon the merits when filed by a plaintiff who has once dismissed in any court of the United States or of any state an action based on or including the same claim. The provisions of this subdivision shall not apply if the plaintiff in such action could not effectuate service of process, or otherwise procure adjudication on the merits.
