50 percent swap used, but "ps auxww" output shows no processes swapped out

Is there a method to determine what swap contents are connected to, if
looking at processes is no longer "a thing"? I have great confidence in
the wonderful FreeBSD documentation, but I find nothing (quickly) in the
manual pages.

The manpage for ps(1), (which I'm sure you're aware of!) describes the
"state" field and its multiple characters and their meanings... that's
what I used for reference.

"W" as 1st character means "idle interrupt thread [of the kernel]."
Subsequent W characters imply swapped-out processes. In subsequent
characters a W indicates that a PID is swapped out.

Thanks for your reply,
