Under certain circumstances, the section break, or actually the blank paragraph containing the section break, may cause an extra page (this might happen below a table, for example). Formatting it as 1 pt font size, exact line spacing 1 pt, zero spacing before/after should fix it. You may also want to format it as hidden text. In fact, you can create a paragraph style with those characteristics and apply it to the empty paragraph in question.
