[Mediawiki-l] Uploading large files fails silently

[Pierre-Marc Fournier]

Hi,

On a mediawiki 1.15.1 linux installation, I can upload files smaller
than 8 MB without problem.

With files >= 8 MB, once the transfer is complete, I am brought directly
back to the Upload form, which is empty. The uploaded file is not in the
images/ directory and not in the list of new files. This is 100%
reproducible. No error is displayed either on the page, or in the apache
logs.

I also had the problem with 1.14.0.

- The maximum php upload size is 40MB so that's not a problem.
- I tried increasing max_execution_time and max_input_time in php.ini.
These timeouts are definitely not reached.
- I tried doubling the maximum memory usage of a php script (now 256MB).
- Updated to the latest apache and php5 from debian testing.

Any ideas?

Thanks
