Mem: 919M Active, 1015M Inact, 134M Laundry, 1606M Wired, 56K Buf, 351M Free

Note: ARC is in Wired.
Note: Buf recounts things in other categories and also is
      small here anyway. So I avoid it.

So:
 919M
1015M
 134M
1606M
 351M
-----
4025M or a somewhat under 4 GiBytes.

This is no where near your reported 15 GiByte+ figures:

real memory  = 17179869184 (16384 MB)
avail memory = 16441286656 (15679 MB)

Looks to me like You already had a big problem start long before
here, losing most of the RAM to a leak already.

Mem: 68M Active, 664K Inact, 13M Laundry, 1567M Wired, 56K Buf, 122M Free

So:
  68M
 664M
  13M
1567M
 122M
-----
2434M or somewhat under 2.5 GiBytes. A loss of roughly 1.5 GiBytes
compared to the above.

Looks like some sort of memory leak that is causing memory to not
be classified as one of Active, Inact, Laundry, Wired, or Free.

What to the figures look like right after booting, possibly both
before and after starting X11 or Wayland (but doing little else
after booting)?
