Thanks for your reply. Yes, looks like that's the issue...unfortunately a reboot resolves it for a while but it always comes back.
Decided to look at an alternative product as VDP is not ready for production use.
The main problem is the resource requirements, which are apparently normal for this software.
I tested it with one backup job and it was using 6Ghz.
There were other things as well, such as poor logging, slow boot time (1 hour for us), password complexity requirements and the DNS error bug during install that made me decide it's ready for use yet.
