[Paraview] pvbatch view.StillRender() crashing

Thu Aug 8 13:39:39 EDT 2013

Still no luck with this new issue, would it be easiest to make a new thread for this (the pastebin's are below) or keep it in here?

The issue is still a crash with my view.StillRender() but now it happens only when using mpirun and pvbatch. If i just use pvbatch without mpirun, the crash does not occur.

Thanks,
~Brian

I went ahead and removed the servermanager.Connect() and that had no change.

What seems to be causing the issue is the view.StillRender() (and/or) view.WriteImage(...) and using mpirun with pvbatch.
(Code works fine when not using mpirun)

I hope someone more familiar with this can help.

Thanks,
~Brian

Hmm, haven't seen that one, but since it's a failed assertion, it may be
that you're attempting something that's not legit.

Are you running this using pvbatch? I don't think you need to call
Connect/Disconnect with pvbatch. Does removing those calls help?

You might also simplify and bulletproof your code by using the functions
in "simple.py" (see source tree). I'm not familiar enough with pv python
to say whether or not your doing something illegal in your code by
accessing servermanager directly.
