BIRD Issues for a Newbie

Hi, very new to BIRD, we use Quagga but I'm looking at implementing both.

I have a Cisco 7200 peering with BIRD, as soon as I enable the peering the 7200 gets the full internet routing table but then hits 100% CPU until I  disable the peering. I have peered the 7200 with Quagga and sent the full table and it has no problems at all, sits at around 40% CPU with the same full table.

Here is the relevant config which is very basic, I've changed most of the settings without any change in the behaviour :(

protocol kernel {
#       learn;                  # Learn all alien routes from the kernel
#       persist;                # Don't remove routes on bird shutdown
#       scan time 20;           # Scan kernel routing table every 20 seconds
#       import all;             # Default is import all
#       export all;             # Default is export none
#       kernel table 5;         # Kernel table to synchronize with (default: main)

# This pseudo-protocol watches all interface up/down events.
protocol device {
        scan time 1000;         # Scan interfaces every 10 seconds

protocol bgp RR_Test {
       description "RR_Test";
       local as yyyy;
       neighbor x.x.x.x as yyyy;
       rr client;
#       export filter bgp_out;
       rr cluster id;
       export all;
#       import filter bgp_in;
       next hop self;
       source address x.x.x.x;
