Tsm4ve v6.4.0.2 ans1236e rc115

I just installed the TSM4VE V6.4.0.2 on a VM Backup server and the first VM they asked me to back up is 9.3 TB in size. It is a file server. Needless to say it fails on the ANS1236E RC115 and there is nothing in the event logs of either the backup server or the VM they asked me to back up. Is there some sort of size limitation regarding the back up of a large VM like this? I have not seen anything in my searches so far.
Any one aware of this or should I just open a ticket with IBM?
