cron/subscriptions.php, lines 43-51

PHP Code:

// time for the reminders
    $subscriptions_reminders = $DB_site->query("
        SELECT subscriptionlog.subscriptionid, subscriptionlog.userid, subscriptionlog.expirydate, user.username, user.email, user.languageid
        FROM " . TABLE_PREFIX . "subscriptionlog AS subscriptionlog
        LEFT JOIN " . TABLE_PREFIX . "user AS user ON (user.userid = subscriptionlog.userid)
        WHERE subscriptionlog.expirydate >= " . (TIMENOW + (86400 * 2)) . "
            AND subscriptionlog.expirydate <= " . (TIMENOW + (86400 * 3)) . "
            AND status = 1
    "); 


If this is indeed your problem, I find it hard to believe it hasn't been corrected yet by the vB devs.
