[Paraview] pvbatch hanging in parallel after WriteImage?

[Favre Jean]

i am having difficulty with pvbatch - compiled with Mesa 7.6 - running in parallel and hanging after the first WriteImage in my python scripts.

I have tested several compilations on different clusters, several MPI (mvapich and openmpi) and still cannot make this work.  It writes the first image and then deadlocks or dies somewhere.

I have no error messages to give me a clue. The pvserver from the same compilation works fine when connected to a client.

This would be a test line:

mpirun -np 12 --use-offscreen-rendering -display :0.0 pvbatch coloredSphere.0.py

are there problems with my syntax, or something I overlooked in this simple example?

thanks for any tip.
