Unbound memory resource consumption?

That's possible.  Of the external dependencies for this package
in our setup the only plausible candidate is nghttp2, and the
installed version is 1.64.0.  The dynamic dependencies of unbound
are:

% ldd /usr/pkg/sbin/unbound
/usr/pkg/sbin/unbound:
        -lunbound.8 => /usr/pkg/lib/libunbound.so.8
        -lssl.15 => /usr/lib/libssl.so.15
        -lcrypto.15 => /usr/lib/libcrypto.so.15
        -lcrypt.1 => /lib/libcrypt.so.1
        -lc.12 => /usr/lib/libc.so.12
        -lutil.7 => /usr/lib/libutil.so.7
        -levent.5 => /usr/lib/libevent.so.5
        -lpthread.1 => /usr/lib/libpthread.so.1
        -lnghttp2.14 => /usr/pkg/lib/libnghttp2.so.14
%

I would think this is a "garden-variety" configuration?
