Tried the CD but cannot get the error to occur in a reasonable time
(ran it for about 3 days; baybe I ought to run it longer by taking a
entire node out of production). There are two issues (1) even during
production the error has a statistical mean-time-between-crashes of
around 1 to 2 weeks.  (2) I am not really sure the diagnostic CD tests
all the relevant calls and CPU functions.

I wish there was a "I do X and the error occurs" That would be simple.
This is the class of non-repeatable one-off errors that is hard to
demonstrate.
