I've set up jFileUpload so it works perfect.
I've set the client to split files in chunks which also works perfect.

The problem comes when jFileUpload tries to "join" the chunks together. Everytime it tries to join the chunks it stops when the result-file is exactly at 128mb. When it reaches 128mb an error comes up, 405 I think or something?

Not error 405 but

"Server error HTTP/1.1 500 Internal Server Error"

Which server-side script are you using ? Our own ? Or some provided in add-ons section such as PHP ?

Yes the php-script from the add-on section.

Did you update $maxsize in the PHP script ? Also, are you sure your server (php.ini) is setup to accept upload (see process_debug.php).

$max_size = 999999999999999999999;

I think that should be enough? I don't want a limit anyway..

Yes the server accepts upload. As I said...
Let's make an example;
Lets say you upload a file that is 300mb it uploads 300mb split in chunks. It´s when they try to "join" together to ONE file that the limit gets at 128mb.

How I know that? Well because everytime I try to do the above and check the "result"-file it ALWAYS stops when the result file is 128mb. After that the error displays as posted earlier.

Ok, if you use process_php.debug. Do you get any error in the log file generated ?

No, no errors at all in the generated log-file.
This is the end of the logfile. Nothing from the end is deleted...

It´s like it just "stopped" recomposing the files...
Still the "500 internal server error" displays in the jUpload-client.

I would like to reproduce the problem. Could you share (with a download URL) your file ? You can send the URL to support(at)jfileupload(dot)com.

I've made some tests on my box it seems to works fine.
Your php.ini seems fine because both "post_max_size" and "upload_max_filesize" are 12M. Your chunksize is 3MB so upload should work. Now, if it's not a disk quota issue (could you check that) then it could be a problem with "max_execution_time" parameter in php.ini. Current value is 30 seconds. If upload and recomposition takes more than 30 seconds then the script will stop. Try to increase it to 300 seconds.
