Bad things can happen, like router reboots due to lack of 
memory for other processes, very slow BGP route processing, 
e.t.c.

For those with fixed ASR1000 systems, don't enable the 
second IOSd software process, as you effectively lose half 
of the control plane memory.

You'll need to consider other entries like IGP, MPLS, 
Multicast, e.t.c., if you have that.
