Or maybe a problem with your OS.
I've no idea, only you can investigate it since I have serious doubts
anyone except you is able to reproduce it.

Hello Tony,

When I wrote the original code about a year ago, readfile seemed to eat
up the memory. Anyway, readfile produces the same error.
It's also there with the latest snapshot.
However, setting the block size to one single byte makes it work.

What I found out is that the file can be downloaded with WGET - full
filesize, but there is a difference between the two files. Maybe a
problem with apache?

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

Honestly saying, I don't understand why you're not using readfile(), as
it does exactly what you're doing manually.

Description:
------------
I open a file of about 600kb, then loop over it with feof and fread,
and echo the read data to the output. In a previous php version (>5,
<5.1.4) it returned random characters, but the file size was correct.
So I upgraded to 5.1.4 to see whether the problem is still there. With
the new version there are no random characters, but the result is much
smaller than the original file. Sometimes it's 73728 (=72*1024) bytes,
somtimes 24576 (=24*1024), sometimes 98304 (also divisible), sometimes
81920 (also divisible). Etc. The previous version also started
producing strange output after reading several block correctly - the
new version simply stops reading.
With the previous version the problem disappered if I set the block
size to 1*1028. With the new version it persists. There is no error
message at the end of the file.

Reproduce code:
---------------
<?php
$filename='../data/temp/temp_output/5741921624893711';
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="test.file"');
$packet = 4*1024;
$buff = ''; 
$F = fopen($filename, 'rb');
while (!feof($F)) {
        $buff = fread($F, $packet);
        echo $buff; 
}
fclose($F); 
?>

Expected result:
----------------
The complete file as a download.

Actual result:
--------------
Part of the file.
