Describe the bug When running bigpoly on py38-rhel7 in https://github.com/equinor/komodo-releases/actions/runs/8608382611/job/23600046726 we got the error:

Too many realizations have failed! Number of successful realizations: 20, expected minimal number of successful realizations: 100
 You can add/adjust MIN_REALIZATIONS to allow (more) failures in your experiments.

Yes, I think it is the same ConnectionClosed group error.
