[Paraview] Paraview client-Server

[Randall Hand]

hrm... I added the headnode to the hostfile (first line), and upped my
scripts to do -np13 instead of -np12.. so now I run

mpirun -np 13 --hostfile ib_all ./pvserver -rc -ch=rhand-svc
--render-module=IceTDesktopRenderModule

The client is waiting on rhand-svc for an incoming connection.. But I
immediately get the following error on the headnode:

/d1/Randall/ParaView-CVS/Servers/Common/vtkClientConnection.cxx, line 334
vtkClientConnection (0x2e67ed0): Failed to get correct ID to assign to this
connection.

Connected to client
Client connection closed.

Any hints?
