[ns] prob. in creating nodes.

["imran ali" <aliimran@rediffmail.com>]

Hi all
         i am getting a basic prob , am generating a topology of 128 nodes but i am succesfull in creating it for 127 but for the magic number 128 its not working.
 the error i am getting is "nodes out of range"
  its not a matter of memory i think.
 code am using is..
  for {set $i 1}{$i<= 128}(incr i}{
     node($i) [ns node]}
