note 101209 added to function.header

hi there, i'm trying to generate a csv file and then force the download. Ok, the core code is this: <?php header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Content-Type: application/x-download"); header("Content-Disposition: attachment; filename=".$fileName); header("Content-Transfer-Encoding: binary"); header("Pragma: public"); header("Cache-Control: private"); ?> then some loop stuff to generate the csv contents then <?php $path = $this->getFullFilePath(); ob_clean(); flush(); @readfile($path); ?> Everything works fine but, as file size grows i start receiving 0kb files to download. Any clue about this?
