Here is what I see when I run pvserver and paraview: mpirun -np 2 /Applications/ParaView.app/Contents/bin/pvserver Waiting for client... Connection URL: cs://sfmrc-678.crha-health.ab.ca:11111 [ after this, two pvserver processes are running, nothing else is printed ]
In another shell: /Applications/ParaView.app/Contents/MacOS/paraview ParaView comes up, and when I try to connect to pvserver, there are no errors reported but paraview hangs and doesn't print any information. If I kill the pvserver processes at this point, then paraview comes back to life and prints the following in the "Output Messages" window: ===== ERROR: In /Users/dgobbi/Work/Kitware/paraview-git/VTK/Parallel/vtkSocketCommunicator.cxx, line 812 vtkSocketCommunicator (0x12819d660): Could not receive tag. 1010580540 ERROR: In /Users/dgobbi/Work/Kitware/paraview-git/VTK/Parallel/vtkSocketCommunicator.cxx, line 561 vtkSocketCommunicator (0x12819d660): Endian handshake failed.
