Lighttpd

Hi,
I'm new to lighttpd, php and fastcgi so if this has already been answered or the problem is with php...

Anwyay, I am using POST to upload files to a server. Uploading any file under 1MB works ok but files > 1MB always fail. They arrive as ~1MB chunks at the server but if theres more than one file chunk the server just deletes them and the operation fails. Ive spent about a day searching the web for solutions now and am a bit stumped!

Example files generated by a 5,857,280 byte file:

-rw-------    1 root     root       594806 Dec  1 17:59 lighttpd-upload-ziIeuD
-rw-------    1 root     root      1048576 Dec  1 17:59 lighttpd-upload-VoLsu0
-rw-------    1 root     root      1056768 Dec  1 17:59 lighttpd-upload-UjbOgs
-rw-------    1 root     root      1052672 Dec  1 17:59 lighttpd-upload-NuJp5E
-rw-------    1 root     root      1052672 Dec  1 17:59 lighttpd-upload-EOn4R6
-rw-------    1 root     root      1052121 Dec  1 17:59 lighttpd-upload-05aBEe

In lighttpd.conf:

server.network-backend = "writev" 

file_uploads = On
pos_max_size = 14M
upload_max_filesize = 7M
memory_limit = -1

The upload page and php has been borrowed from http://www.tizag.com/phpT/fileupload.php

On the upload page:

<form enctype="multipart/form-data" action="uploader.php" method="POST">
        <br />
        <input type="hidden" name="MAX_FILE_SIZE" value="10000000" />

        Choose a file to upload: <input name="uploadedfile" type="file" /><br />
        <input type="submit" value="Upload File" />
</form>

uploader.php:

<?php
   $target_path = "/var/uploads/";
   $target_path = $target_path . basename( $_FILES['uploadedfile']['name'])

   echo '<pre>';
   if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)
        echo     "The file ".  basename( $_FILES['uploadedfile']['name']).
                " has been uploaded\r\n";
   } else {
      echo "There was an error uploading the file, please try again!\r
      print_r($_FILES);
   }
    print "</pre>";
?>

Im using lighttpd v1.4.20, php 5.2.3 cross-compiled onto an Axis Etrax 100LX running Linux 2.4.31.

Any help would be appreciated, thanks!
