Howdy Venkat,

I think your computer is not set up to support large files. See this FAQ, and 
run the test it suggests on your disks:
http://www.unidata.ucar.edu/software/netcdf/docs/faq.html#Large%20File%20Support12

It could also be that you are exceeding the limitations of the netCDF classic 
format. If so, you would get an error code from the library:

#define NC_EVARSIZE     (-62)   /* One or more variable sizes violate
                                   format constraints */

If this is happening, you might try reading the Large Files section of the FAQ:

Thanks,

Ed
