CGNS Reader failure fails if file size above ~2.1GB
I'm getting an error when attempting to read a CGNS file that was created in ANSYS Fluent. I've narrowed it down to a variable limitation issue.
If I export 59 variables from Fluent into a CGNS, Paraview's CGNS reader works perfectly.
If I export 60 variables, the CGNS Reader fails:

After testing a lot of different export settings, it doesn't seem to matter which 60 variables I export, it just can't do that many.
