Two things I've run into with this coming from 9.2-STABLE....
1. I am getting errors coming from mail transmissions to certain MX relays
-- and only those relays. One of them is (ironically) mx1.freebsd.org,
which precludes emailing the list from my primary email address! The error
logs in the maillog file show:

Permission denied -- on a socket? As root? What am I missing here?
(Shutting off TLS does not resolve this.) However, this is not universal;
it only impacts *some* emails....

That one went through successfully....
This is new; I didn't have any trouble on 9.2-STABLE at all. Ideas?
The other issue is that I am running into bizarre wired memory behavior. I
have ZFS on the box and it was wiring down ~20GB, driving the system into
paging. I dropped arc_max to 16GB as a hard limit, it's currently showing
15GB, but...
20531152 wire
zfs-stats -A shows:

Ok, where's the rest coming from? There's nothing in the shared memory
segment list that appears to be related.
Is there a memory leak in here somewhere?
