Can only download 1.90mb

[ahmtech123]

Weird issue. I dont know if this is a php or apache or maybe mysql issue. When linking files using a mysql query I can not download anything over 1.90mb..the file just stops and says complete at 1.90mb. I can view items in the upload folder and can download items with an absolute link

http://www.foo.com/download.pdf

i use an upload script to upload them and I verify that the size is identical as the orginal. 6.5mb.

so far I have change upload size in php.ini, restarted apache, installed the script again from scratch. I have not touched anything in mysql.

Again this is a third party software I am using. It uses the smarty templating engine.

Any ideas would be appreciated.

Here is my code:

$attachment_dir = './var/attachments';

if( !$lore_system->db->id_exists( $_GET['id'], 'lore_attachments') )
{
	$lore_system->te->assign('error_message', 'invalid_attachment');
	$lore_system->te->display('error_message.tpl');
	exit;
}

$attachment = $lore_db_interface->get_attachment( $_GET['id'] );
if( !file_exists( "$attachment_dir/$attachment[filename]" ) )
{
	echo "File $attachment[filename] not found.";
	exit;
}
$lore_db_interface->increment_attachment_downloads( $_GET['id'] );

//$content_disp = ( eregi('', $_SERVER['HTTP_USER_AGENT']) ) ? 'inline' : 'attachment';
$content_disp = 'attachment';
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header('Content-type: ' . $attachment['filetype']);
header('Content-Disposition:  ' . $content_disp . '; filename="' . $attachment['filename'] . '"');
header('Content-Length: ' . filesize("$attachment_dir/$attachment[filename]") );
header('Accept-Ranges: bytes');
//header("Content-Transfer-Encoding: binary");
@readfile( "$attachment_dir/$attachment[filename]" );
