[Paraview] server error msg

[Jack Gundrum]

Hi,

I am running a paraview server connecting to a client as follows

mpirun -v -machinefile /etc/mpich/machines.LINUX -np 13 
/usr/global/paraview/bin/paraview --server
running /usr/global/paraview/bin/paraview on 13 LINUX ch_p4 processors
Created /home/jsg3/PI15832
Listen on port: 11111
Waiting for client...
connected to port 11111
Client connected.
Process id: 0 >> ERROR: In 
/usr/global/src/paraview-1.8.3/VTK/Rendering/vtkXOpenGLRenderWindow.cxx, 
line 326

p0_16143:  p4_error: interrupt SIGSEGV: 11
Killed by signal 2.


This does work fine most of the time except when I try to create 
contours from my data set?
I am new to Paraview so any help would be help:)
