I am in a similar situation and am having the same issue, word for word (with the exception of the username).

Did using RHEL7 work? I am using a large shared cluster running RHEL6 with some nodes running RHEL8, the RHEL8 ones producing the identical errors. I have the ability to use nodes with RHEL7 by using a container, but it is a lot of additional steps and effort.

Any feedback on the RHEL7.x suggestion would be a great help.

Thanks Devin
