PHP foreach stops after first iteration with no apparent reason

I'm having lots of trouble with a foreach cycle in PHP.

It's not the usual "break\exit\return\whatever;" issue and I'll explain you the reason:

class Example {
     private function generic(/* args */) {
          global $db;
          $result = false;
          /* a series of if and functions, mysql transactions and 
             "throw new Exception" on rollback */
         $notif = new Notification();
         $notif->send(/* params */);
         /* if commit succeded > $result = true; */
         return $result;
    }

    public function start() {
         $list = array("abc" => array("foo" => "bar", "foo2" => "bar"), "def" => array("foo" => "bar", "foo2" => "bar"));
         foreach($list as $x => $y) {
             $this->generic($x, $y, ....);
         }
    }
}

The issue seems to be with $notif declaration and\or $notif->send() function.

I tried to try\catch the entire generic() function and also the send() function but no Exception gets thrown up.

The send() function is nothing more than a series of queries and eventually (on user request) it sends an email notification via swiftmailer.

Another detail I can give you is that notification gets successfully sent and everything seems to work just fine on the first iteration, but then the foreach stops.

As I mentioned before: there are no "exit();" or "break;" or "return $x;" at some weird point in the function and so on...

Do you have any idea of what could the issue be, or how can I locate the issue?
