Hi, I want to open CASE file. The file size is 2.5GB including other files.
When I use 1core, I can open it.
But I use over 14core, I can’t open it. And crash pvserver.
Do you know the solution?
The machine which work pvserver has 36core.
I attached ERROR\_LOG.
[pvserver\_error\_log.txt](https://discourse.paraview.org/uploads/short-url/s3JG19f7QkPlxz8yx9EcBQLpg0e.txt) (119.9 KB)
I try to open example paraview file with 36core.
It can open.

You will need to share your dataset.

Hi Mathieu Westphal,
The dataset is not mine. So I can’t share.
It is possible to try the settings your order.
Have you heard similar trouble?

Sadly, without data this will be complex to debug
