    The ip_dst_cache seems unreasonably large. Unless your desktop is a
    backbone router or something.

    Lots of DST entries can result on any machine actually. We create one
    per source address, not just per destination address. So if you talk
    to a lot of sites, or lots of sites talk to you, you'll get a lot of
    DST entries.

    Regardless, 80MB _IS_ excessive. That's nearly 400,000 entries.
    It definitely indicates there is a leak somewhere.

    Although it say:

    ip_dst_cache 19470 19470 4096 1 1

    Which is 19470 active objects right?

    There is a known aparent issue with IPV6, there is some DST
    leak there, but that is irrelevant here since we're clearly
    talking about the ipv4 dst cache.
