It looks like there is a memory issue somewhere. We will track it. However,
I have to say that creating 1000 individual line sources and 200 sphere
sources, all of which have displays, is not a common use case for ParaView
or VTK and is not something that will be efficient anytime in the future. I
suggest finding an alternative way of doing this. For example, it would be
way more efficient to have 1 source that takes a list of point tuples and
creates one vtkPolyData that has all of the lines. Same is true for spheres.
