I'm not 100% positive if this will be reproducible, but I am noting it here in case this persists / it may be slightly helpful to someone in the future even if I end up closing this later today.
This same dataset has been successfully built numerous times this week, so I'm not sure what changed.
Error 1:
Segmention fault that appeared after the file download step completed.
Then I rebuilt the docker image with no caching.
Error 2:
No Segmentation fault, but the docker container is hanging indefinitely around the same step.
