[TYPO3-english] .t3d import error [was it too big?]

[Joydeep Bakshi]

Hello list,

I'm working with typo3 4.5.0 along with the following settings globally
(php.ini)  

memory_limit : 9048m
upload_max_filesize: 358M
post_max_size:	512M

But when I try to import a 99MB t3d I get an error

```````
Upload status:	Failure: No file uploaded - was it too big? Check system log.
``````

No relevant log found at apache level.

What can be the issue ?
Any solution/clue is most welcome.

Thanks
