Dear Ray:
With the current version of the code, there are not many options.
Basically, you need to change the value of input keyword max_memlt (https://docs.epw-code.org/doc/Inputs.html#max-memlt) so that this value is larger than your memory footprint.
PS) Usually you need to reserve more memory per node (for instance, by using the smaller # of MPI tasks per node) along with the above prescription.
Sincerely,
H. Lee
