interesting thats the same message I got.

Possible that a reboot is needed to after platform shell has been added
to the config but I cannot boot the box in production at the moment.

I did find following command:

    monitor platform software process rp active

on

   http://www.cisco.com/en/US/products/ps9343/products_tech_note09186a0080af252a.shtml

that gives following top like output:

And yes I can see that the iosd-image has 2G of ram on the outside in the linux.

although it advertises the following from inside the ios:

   cisco ASR1001 (1RU) processor with 1207124K/6147K bytes of memory.
   9 Gigabit Ethernet interfaces
   32768K bytes of non-volatile configuration memory.
   4194304K bytes of physical memory.
   7782399K bytes of eUSB flash at bootflash:.

It seems that a lot is getting eaten inside the ios itself.  The numbers most propably
measure different things like executable and data segment sizes. We would need an
architecture whitepaper to understand this.

The other interesting question is what function the fman_fp_image process has. 
It seems to have the better part of the other 2 gigs in the box.

licensing fun.
