[Koha] Strange behavior when sending overdue notices.

Dear koha-developers, I recently updated my koha installaton from 3.08.06 to 3.10.00 in ubuntu 12.04 server(DEBIAN PACKAGES). But when i run overdue_notices.pl I found astrange behavior. It sends same mail to different patrons who have over dues. That means e-mail address and content are mismatched. Is there is any solution to fix this problem.
