[Paraview] Multiple servers

[pat marion]

Sorry,  I can't give you a guess what the problem might be.  Double check
that you used the same source to compile paraview and pvserver on the
various machines, and the same mpi library versions.  Is one machine 32 bit
and one 64 bit?  Does paraview work as expected if you create objects from
the Sources menu?
