Can you try with 64 bit OS?
32 bit OS/PHP intval() return maximum ~2147483647.

also try to patch Sapi.php to add

         $contentLength = $response->getHeader('Content-Length');
          if ($contentLength !== null) {
 +            $contentLength = intval($contentLength);
              $output = fopen('php://output', 'wb');

No sorry i can't try with 64 bit OS i only have Owncloud installed on my Raspbian.
The patch worked fine at first but the download stopped at 2 GB which is coherent with your explanation.

So i tried to remove the $contentLength on stream_copy_to_stream call (sorry i didn't find how to display the line breaks) :

if ($contentLength !== null) {
            $output = fopen('php://output', 'wb');
            if (is_resource($body) && get_resource_type($body) == 'stream') {
                stream_copy_to_stream($body, $output);
            } else {
                fwrite($output, $body, $contentLength);
            }
...

That fixed my problem but i don't know the collateral effects...
Should I change it in fwrite call too ?

Moreover, I didn't have this problem with owncloud 8.2.3 and PHP 5. Which one of these upgrades bringed the problem ?

Thanks for you help :)

3rdparty problem. Closing here.

[Diak]

it means the problem will not be solved because it concerns a 3rd party API included in Owncloud and not Owncloud core itself ?

[nickvergessen]

Well we can't fix it, once the thridparty (Sabre/http) fixed the issue, we will simply update it.

[Diak]

Ok I understand but when i used Owncloud 8.2 and PHP 5 i didn't have this problem.
Which one of these upgrades caused the problem for me ? Is it owncloud upgrade including Sabre/http upgrade who caused my problem ?

I'am asking because if some day i have to reinstall my raspbian, i need to know which versions of the components i shoud install to avoid issues.

[jswhisperer]

I'd be keen to hear of some offical Rasbian support for the core.
