Try using stream_copy_to_stream() instead. I find is has fewer problems than readfile().

set_time_limit(0);
$stdout = fopen('php://output', 'w');
$bfname = basename($fname);

header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$bfname\"");

$filein = fopen($fname, 'r');
stream_copy_to_stream($filein, $stdout);

fclose($filein);
fclose($stdout);
