Woohoo, I'm not the only one...
Raising the memory limit and setting output buffers to 8192K in php.ini
worked. Though I am not happy with that solution. Indicates to me
some mmap error of some sort. Maybe something in glibc is mmapping the
file and creating artificially large buffer spaces in memory.
Here's what I found to "work"...though it still indicates a
buffer/memory bug to me:
function send_file($dir, $file){
$fp = fopen("$dir/$file", 'rb');
header("Cache-control: private, no-cache, no-store,
must-revalidate");
header("Pragma: no-cache");
header("Content-Type: application/x-stuffit");
header("Content-Length: ".filesize("$dir/$file"));
header("Content-Disposition: attachment; filename=\"$file\"");
header("Connection: close");
while(!feof($fp) and (connection_status() == 0)) {
print(fread($fp, 8192));
flush();
}
$status = (connection_status() == 0);
fclose($fp);
return($status);
}
This works with an 8M memory limit (I really don't want to have it any
higer, otherwise concurrent downloads will absolutely hammer on the
server) but needs output buffering turned on at 8192K.

I get pretty wierd results with this script:
<?php
session_start(); // Comment this and it works fine..
$fp = fopen("test.zip", 'rb');
rewind($fp);
header("Cache-control: private"); // another fix for IE
header("Content-Type: application/x-stuffit");
header("Content-Length: ".filesize('test.zip'));
header("Content-Disposition: attachment\; filename=\"test.zip\"");
header("Connection: close");
$fr = fpassthru($fp);
?>
php,ini:
session.use_trans_sid = 1
memory_limit = 1M
And sending some file around 1M size will make it fail..

Try raising the memory limit to 15-20 megs and see if the problem
persists.

Do you have session.use_trans_sid option enabled in your php.ini?

In php.ini:
zlib.output_compression = Off
memory_limit = 8M
output_handler =
I get the errors with any 'modern' graphical browser (Mozilla,
Netscape, IE...). Links works just fine though. I'm now leaning
towards something wrong between fpassthru() and session_start().
Also, in my apache logs I'm getting something similar to:
[Tue Feb 25 15:35:06 2003] [info] [client XXX.XXX.XXX.XXX]
(104)Connection reset by peer: client stopped connection before rwrite
every time a download fails. And its not my users hitting the stop
button.
