When I try to upload a PDF file at say 30,814,410 bytes (30.8 MB ) I get this error:

The upload bar goes up to 100% but then the above happens

Why is that and how can I solve it?

Is your upload limit set in php higher than 30.8MB ?
Check phpinfo
admin.php?tools/phpinfo and if not adjust the value in php.ini

And also check the forum max. upload limit

If you're unsure, you need to contact your host and ask them what the max_upload_limit an post_max_size value is in PHP and ask them to increase it to a higher value than the size of the PDF you're trying to upload.
