Niladri,

I would bet that if you used 600 Ry on a single processor the error would
not exist :o). In case you are running parallel siesta serially and get no
error, it becomes rather clear that the error happens from using netcdf with
a parallel run - nothing whatsoever to do with mesh cutoff. There are only
two solutions: either you recompile netcdf to have it give you no error when
running the code in parallel, or you simply don't use it in parallel. Right
now I don't remember if there's an fdf flag to disable netcdf output, but if
there are none, I suggest you remove every reference to it in the arch.make
file and recompile siesta without netcdf support.

Have a nice weekend,

Marcos
