What CPU are you running? That seems high for 45Meg on an RSP4. Check
out my discussion from yesterday to see if you're running dCEF on it all.

Are you peering to two different ISPs, or just doing two pipes into one?
First case, you'll want 256Mb on your RSP and 128Mb on your VIPs. Second
case, why even use BGP at all when you can use static routes and CEF
load balancing across it, or you can use BGP and just pull in a default
and use multipath to load balance two routes.

Need more info on your hardware and your config to get a good idea of
what you'll need to change.
