  since  this  is all embedded application (ukern) running on the
  IP-II  processor it is not like a normal user_land process like
  you  have  on  the  Routing  Engine.  This  requires  a  closer
  inspection  and  I suggest in this case that you send a note to
  support at juniper.net  so  we  can follow this up in more detail.
  Please send along "request support information"

  I just wanted to bring over the message if you want to know how
  much  memory is used on the IP-II processor you need to look at
  the  heap value and not at the buffer value. Heap is a function
  to  manage  memory  allocation. if you look on any search engine
  for heap&memory you will find plenty on detailed explanations.

  thanks
