We've tested the netCDF library with very large files (e.g. 2Gbytes).
Does you disk have enough room for more than 105 Mbytes?  You can
discover the available free space on your disk with the "df" utility:

    $ df -k /tmp
    Filesystem             Type  kbytes     use     avail  %use Mounted on
    /dev/root               xfs  4307148  3300104  1007044  77  /

The above file partition has 1.007004 Gbytes of free space available.
If I tried to create a 1.5 Gbyte file on it, I would expect to get a
"file too big" error.
