[Paraview] PV 2.6.0 Killing MPICH

[Kent Eschenberg]

I was looking at a 2D array of about 6000x6000 values and 
things were looking correct. I turned off composite and 
after a minute the server printing the following then crashed:

======
Process id: 2 >> ERROR: In 
.../src/VTK/Filtering/vtkExecutive.cxx, line 757
vtkStreamingDemandDrivenPipeline (0x6cfe310): Algorithm 
vtkXMLUnstructuredGridReader(0x6cea090) returned failure for 
request: vtkInformation (0x6cfef70)
   Debug: Off
   Mp0_3205:  p4_error: alloc_p4_msg: Message size exceeds 
P4s maximum message size: 477346479
======

It looks like PV was trying to send something big instead of 
multiple smaller pieces. Does it check for the maximum MPI 
message size?

    Paraview 2.6.0, client and server
    Using four x86_64 processors
    Red Hat Enterprise Linux WS release 4
    MPICH 1.2.7p1 with the ch_p4 device model
