Here is the warning on a fresh VM with 8GB:

    # sysctl hw.physmem
    hw.physmem: 8551202816
    # service local_unbound onestart
    Starting local_unbound.
    [1759883902] local-unbound[3237:0] warning: setsockopt(...,
SO_SNDBUF, ...) was not granted: No buffer space available
    [1759883902] local-unbound[3237:0] warning: so-sndbuf 4194304 was
not granted. Got 9216. To fix: start with root permissions(linux) or
sysctl bigger net.core.wmem_max(linux) or kern.ipc.maxsockbuf(bsd)
values. or set so-sndbuf: 0 (use system value).

    Waiting for nameserver to start... good

If we configure it with "so-sndbuf: 0" the warning goes away.
But, nevermind if I'm the only one seeing these warnings. It was just
a basic local_unbound test.
