Are you using LDAP? I notice your dhcpd is built with LDAP libraries.
It might be a good idea to try to run it without LDAP. And also to
build it with debugging symbols to enable a sensible backtrace after
a crash.

For comparison, on my FreeBSD 7.3-STABLE box (without LDAP), dhcpd
is only linked with two libraries:

% ldd /usr/local/sbin/dhcpd
/usr/local/sbin/dhcpd:
        libcrypto.so.5 => /lib/libcrypto.so.5 (0x28118000)
        libc.so.7 => /lib/libc.so.7 (0x28271000)

For me (failover config, around 120k leases) ISC DHCP 4.1.1 is rock
stable.
