Me too, although I would still regard my elisp as extremely
rudimentary. Your above example is exactly what I'm seeing.
How is expiry processing supposed to work now in respect of nov
lines that do not have downloaded articles? Is it that all nov lines
with an article number less than the lowest numbered expire-able
history line (for a given group) are/should be deleted? I guess I need
to watch a little more closely, but I'm sure that *not* all my old nov
lines are being deleted, and, as previously mentioned, I have
sometimes seen a glut of low numbered nov lines appear some-way down my
.overview files, seemingly out of sequence???
I'm currently cleaning up my .agentview and .overview files by hand
when required. I do a `sort-numeric-fields' on my .overview, this
invariably brings the errant nov line to the top (the line number in
the `strange nov line message' can be way out), and delete all those
up to the article number that corresponds with the first article
number in my .agentview.
I hope someone can figure out what's happening here - expiry is a
good thing if you want to get any reasonable performance back into
summary preparation.
