[Paraview] ParaView 4.3.1 client runs X out of memory

[Jeff Becker]

Hi. I created a VTK unstructured grid (.vtu) file for a 500 by 500 by 
500 point data set. In order to visualize it, I fire up 8 pvservers on 
my GPU multicore backend node using:

  mpirun -np 8 pvserver --client-host=XXX --use-offscreen-rendering

and connect to the root server from my ParaView client. I then open my 
vtu file and hit apply, I can see the file gets read in, and then 
nothing much else happens except X on my client grows to fill all of 
memory, and my client system (my desktop) becomes unusable. I'm guessing 
that the client is getting overwhelmed with X requests.

What am I doing wrong, and how to fix?

Thanks.
