I have a user that is using a user subroutine on linux (Oracle Linux 8).

The job runs fine using abaqus 6.11. However, when they try to run on abaqus 2019 the job just hangs.

abaqus job=main user=user_subroutines.f cpus=4 

I have added verbose and setting ABA_PARALLEL_DEBUG but I am not getting any idea why this is happening.
