It sounds faintly like this old Linux nfs client bug where the client just pounds the nfs server over and over again, regardless of requests. I usually spotted it by check if the client is an older 2.4 kernel (common package in RedHat7.3). The quick fix is to go to TCP. The longer term is to upgrade your kernel to something a bit more recent.
But that is a linux only thing. And only on older kernels (something like 2.4.9..). If that's not your client, I'd have to know more about what you are seeing.

We are seeing extremely high network traffic from single clients to nfs mounted filers. In most cases running nfswatch on the client shows almost all of the traffic due to "RPC Authorization". We are talking 50-80Mbits of traffic with nothing sticking out on the clients process list. Has anyone seen weird high network traffic via nfs over udp?
