I restarted emacs with the increased value in my .gnus.el, and
then it worked.  But I fear this is just delaying the problem for a
decade or two.  

Here's my guess at the bug:

In gnus-registry.el:

(defun gnus-registry-fixup-registry (db)
  (when db
    (let ((old (oref db :tracked)))
...
      (oset db :max-hard
            (or gnus-registry-max-entries
                most-positive-fixnum))
...
      (oset db :max-soft
            (or gnus-registry-max-pruned-entries
                most-positive-fixnum))

If the user sets gnus-registry-max-entries but not
gnus-registry-max-pruned-entries, then the soft limit might be (much)
higher than the hard limit.  Maybe the last line should be changed to
replace `most-positive-fixnum' with something like `(oget db :max-hard)'
(just guessing at how to read a stored value).
