Any one have this problem? MSCS Share access lockout when a user upload 800M+ data

Using two Dell 1650 and a powervault 220S, Microsoft Clustering to provide share disk space.

 

Currently if anyone is uploading data to the share (magic number of 800M+) the cluster locks out all users access to the share accept the user who is uploading the data and will not allow acces again until the user is done with upload. 

 

I have try searching on the internet and dell and and microsoft sites and really have not found any real helpful info.  Have tried contacting support and it pretty much pointing fingers.

 

Any info or suggestion would be appreciated.
