Yes, this does indeed look similar to that problem report and the
mail thread refrenced therein.

Going back to my own submission I find:

  127927 VM pages: 76357 active, 38080 inactive, 2422 wired, 7 free
  pages  73990 anon, 37343 file, 4129 exec

    swpages=128000, swpginuse=128000, swpgonly=127997, paging=0

so I'm actually also out of virtual memory, since all swap pages
are in use.  However, "something" ought to be able to find a
victim to kill or do something else (steal an exec page?, or
steal a non-modified anon page, if there are any...), but, yes, I
guess this is the well-known problem that NetBSD doesn't behave
quite robustly when running out of virtual memory...
