My Apache crashes with error code:

[Tue Mar 19 19:09:47 2002] [info] master_main: Child processed exited prematurely. Restarting the child process.
[Tue Mar 19 19:09:47 2002] [info] Parent: Created child process 1080
[Tue Mar 19 19:09:47 2002] [info] Parent: Duplicating socket 484 and sending it to child process 1080
[Tue Mar 19 19:09:47 2002] [info] BytesRead = 372 WSAProtocolInfo = 2006620

reason is:

$filename = "d:\\web\\kontakt\\test.jpg";
$fp = fopen($filename, "rb"); 
while(!feof($fp)) { 
  $attachment .= fread($fp, 1024); 
} 
fclose($fp); 

OR: 
$filename = "d:\\web\\kontakt\\test.jpg";
$fd = (fopen($filename, "rb"));
$attachment = addslashes(fread($fd, filesize($filename)));
fclose ($fd);

There's no problem on a Linux System.

What should i do?
