One problem is that the process on the second node is trying to open an
X window, and the xhost is refusing the connection.  ParaView does not
open up an x window until it needs to composite the data, which is why
it doesn't happen until you load a "larger" data set.  Change the
permissions of the xhost on process 2 to allow the mpi job to connect to
it.
