There is one eBGP feed with 499k routes, and 3 internal MP-BGP sessions
with 90k, 340k and 163k routes respectively.


There's about 380MB of free process memory:

The box runs 3.9.0S.

Other boxes in similar configuration run with 350 and 320MB of free process
memory.

I would've liked to enable BGP best external/PIC Edge, but I think that
would exhaust memory on those boxes with RP1, so I did not enable it.
