Download failed on >2Gb files on SMB/CIFS Storage

Hello everybody,

I am trying to setup owncloud as a way to share files with external customers, and I encounter one issue so far:

I have configured external storage with SMB/CIFS to one of our windows servers (64bit machine) where employees can copy their content and than share it over oC. Everything is working fine, except for files larger than 2Gb, in which case the download stops at the beginning and the downloaded file is only 1Kb.

If the files are located on a local storage on the oC server, the download works as expected, so no issues there.

I would really appreciate some help on this.
Thank you!

Server configuration
Operating system:Ubuntu 14.04 LTS
Web server:Apache2
PHP version:5.5.9
ownCloud version (see ownCloud admin page):ownCloud 9.1.3 RC1
Updated from an older ownCloud or fresh install:fresh
Special configuration (external storage, external authentication, reverse proxy, server-side-encryption):
SMB/CIFS external storage to windows 2008R2
