In addition to Claudio's reply I'd like to add; in the case where one of the bgpd processes is killed by a signal (SIGBUS in this case), you may be able to get more information from a coredump, however these are not enabled by default for privilege-separated daemons like bgpd. If you'd like to preemptively enable these in case there are any future problems, you can set kern.nosuidcoredump=3 in sysctl.conf, and mkdir /var/crash/bgpd (safest owned by root and chmod 700).
