Great! Software is a game of successive approximations - I'm glad we are
zeroing in on what you need to work! ;-)

OK, you do not have the "known" large file problem. You have something else.

Firstly, let's make sure that large files are possible on your file system. Can
you run the following command, and check the output?
dd if=/dev/zero bs=1000000 count=3000 of=./largefile

This should create a 3 GB file (called largefile). Check its size with the ls
-l command, then remove it.

(If you're curious this is described here:
http://www.unidata.ucar.edu/software/netcdf/docs/faq.html#Large%20File%20Support12)

This large file problem is not a netCDF-4 problem, it is a netCDF-3 problem as
well. That is, even very large classic format files are not working for you.
This makes me suspect that there is something about your OS, disk, or the
netCDF configure script which is causing this. Can you send me the config.log
file for the large file test build?

Thanks!

Ed
