Make sure login.conf memory limits for the daemon class (or the _bgpd class on a newer OS version using /etc/rc.d) are high enough. If your limits are insufficient for the size of routing table then obviously you will have a problem. But also there is a bug somewhere, possibly to do with nexthop changes, which can result in very rapidly increasing memory use.
