XF 1.5 Unable to attach large file

When I try to attach a large file (134MB), I get this message.

The following error occurred
There was a problem uploading your file.

I am using Plesk and have my php settings set to:
post_max_size 2048M
upload_max_filesize 1024M

Presumably you have also set the appropriate limit in the ACP (although I would expect a different error message if that wasn't the case).

You may also need to adjust some MySQL values, such as:

In general, your sysadmin or host would have to investigate why large files are being rejected by the server - there are a lot of variables which are involved.
