--- Comment #10 from Mark Millard <markmi at dsl-only.net> ---
I've reduced the testing context to the following
type of example (no longer involving buildworld
buildkernel):
# sh
# sh
# sh
. . .
# sh
(So a bunch of nested sh's in an ssh session that
will mostly be swapped out. I happened to have
done this under 2 users for the example material
below: on I did an su first. Plus I had another
session without such a nesting but with an su.)
After forcing these to mostly swap out (see below)
I use ^D to exit a currently interactive one. Then
the rest of the swapped out ones from the nesting
get the tsd_booted failure.
So, for example:
# stress -m 1 --vm-bytes 1536M
The context is a PINE64+ with 2GB of RAM. The above
was enough in my context to cause the needed swapouts:
# ps -aOuser,flags
