Nek5000reader load error for Large dataset

Dear commnuity:
I try to load a large dataset (around 50 GB) using Nek5000reader by mpi. I loaded it on my CentOS workstation, which has 256 GB memory and 40 CPUs.

It threw such a problem 956: seekg error at read_location = -1050980344", how do I solve this problem?
