here is a link to a scene I can't render on the "non-stable station". Very simple scene but with an alembic object.

Generaly I don't work on very complex scenes.
My impression is that problems occurs when geometry or materials evolves. I have a big scene (limit in memory) but with a single camera animation and there is no problem.
Yes probably GPU/Driver probleme.
On the other hand the render queue problem occurs on the two stations even on the "stable station".
I will try to reuse it after update (driver and plugin), and this time will collect the bug reports.
