DLNA and Large Files

I’ve got a GL-AR750S-EXT (Slate) router.
I’ve enabled Multimedia file sharing on a 64GB microSD card.
I’ve copied an 8 GB file onto the microSD card.

When I ssh into the router I can see the file on the /mnt/sda1 folder.

However when I try to access the DLNA server with VLC the file is not listed.
On an iOS device the file list never loads
On OS X the folder is empty.

Is there a file size limit of the DNLA server?

Thanks
