Hi all,

I'd like to use MPI pvserver to take advantage of some 48 core nodes we
have on our cluster. There's not much in the way of GPUs, so I've been
trying to take the route of using OSMesa with --use-offscreen-rendering.
The pvserver seems to start well, but as soon as a client connects, the
thing aborts. In particular, if I try to use pvbatch with a basic sphere
rendering, the pvserver crashes on running the Render(view) part of the
script. Pasted below is the error.

Does anyone have any insight on this?

Waiting for client...
