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. -- Mike.
