Ken,

First, I don't think you can practically produce JP2 files of this size
using JasPer.  As far as I know it needs to hold everything in RAM.   You
normally need the JP2KAK driver to produce large JP2 files.

Second, are you sure you are writting in JP2 format?  It is in the middle
of the TIFF driver where you run into problems.  What was the command you
issued?

Third, is VSI_LARGE_API_SUPPORTED defined to 1 in gdal/port/cpl_config.h?
If not, you won't be able to operate on files larger than 4GB.  If it is
and you are unable to product TIFF files in the 2-4GB range there is an
issue I would like to look into.

Best regards,
