Upload fails @ >10MB

[mittra]

I am trying to use the web interface to upload a 89.8MB file as a test before deploying to my users. Upload is failing at 58%. This file is roughly 10% the size that will be typically uploaded by my users and I am using FTPBox so my users do not have to install an FTP Client or perform the upload via the command line.

In system/classes/upload.php I have already increased $sizeLimit to 5368709120 (5GB) to match my php.ini settings "upload_max_filesize = 5120M", "post_max_size = 5G", and "output_buffering = 5120".

PHP Version: 5.3.28
System: Linux www2.g1.pair.com 2.6.32-50-server #112-Ubuntu SMP Tue Jul 9 20:45:08 UTC 2013 x86_64
Browser: Chrome Version 33.0.1750.154 m

If there additional information I can provide that will assist in resolving this issue, please let me know.

UPDATE:

I tried smaller files to determine where the error seems to occur. While uploading a 14.6MB file I got a message that the "File is too large":

Curious. I found on line 120 of upload.php where that error message is generated, so I included in the error message the variables for $size and $this->sizeLimit and found that FTPBox seems to think the max size limit is still 10MB (10485760 bytes).

Where else is that limit set?
