Larger file uploading >6mb fail

[Soma]

I have a problem with uploading files (not images) to a file upload with ajax.

Everything below ~6mb works well, after that it doesn't complete upload. The upload max filesize and post max size is ~30mb. BUt on another hosting I have a PW that have 8mb+ files.

So is there any other setting on the server that could limit this?

I get this on the response header:

HTTP/1.0 500 Internal Server Error Date: Wed, 05 Sep 2012 12:50:10 GMT Server: Apache/2 X-Powered-By: PHP/5.2.4-2ubuntu5.25 Content-Length: 0 Connection: close Content-Type: text/html

wild guess .... execution time of scripts ?

Nope. Upload would take 5-10 seconds and it's set to 30. I've set it via htaccess to 3 hours to test. It still does not work.

max_execution_time AND max_input_time set to 30?

I remember also had once a problem when setting these values too big.

Another thought: Mod_security active?

Thanks, but we found it's the memory was to 32mb, moving up did the trick.
