Hi Randy,

There's an FAQ on this:

  Why do I get an error message when I try to create a file larger than 2 GiB 
with the new library?
  
http://www.unidata.ucar.edu/software/netcdf/docs/faq.html#Large%20File%20Support12

that has a few reasons this could occur that are not releated to netCDF
and a test using the dd utility that determines whether the file system
you're on supports large files.

Is it possible you are using an older version of IDL built with just netCDF-3
support?  You're right that netCDF-4 files should not have any practical file
size limits.
