Client dedupe client-side resource issues,

I have a server 2012 server with works well with Media side dedupe configured . My environment is a Netbackup 7.6.0.1 

The server 2012 client has 4CPU and 16GB of RAM 

When I have client side dedupe configured Status 41 occurs after a significant amount of data has been transferred, or at the end of the backup,

Looks like its a client-side resource issue ??  but cannot figure out what i need to do ??? is a case of More CPU or More memory or ???
