[Paraview] pv 3.0.2 max number of parallel processors?

[Stephen Wornom]

pv 3.0.2 functions correctly with up to 16 partitions.
What I try 32 partitions using 8 processors  I get the error

[3]   Done                    /usr/local/paraview/bin/paraview -dr

/tmp/rpmbuild/BUILD/paraview-3.0.2/Servers/Common/vtkServerConnection.cxx,

vtkServerConnection (0x4be3290): Server Connection Closed!



[4]+  Broken pipe             /usr/local/paraview/bin/paraview -dr

Is there a limit to the number of processors that can be used?
