Do you still have the RHEL 7 machine? Could you please share the
sessionInfo() output at least from the RHEL 8 machine but, if possible,
also from the RHEL 7 machine?

Could you identify and share the parts of the script that launch the
computation in parallel?

solved in the mailing list.

THanking you,
