When a summons fails of sufficient service or return by unavoidable accident, or default, or negligence of the officer to whom it was delivered or directed, or the action is otherwise defeated for any matter of form, or by the death of either party the plaintiff may commence a new action on the same demand within 6 months after determination of the original action; and if he dies and the cause of action survives, his executor or administrator may commence such new action within said 6 months.
