Huh?
What're you claiming as the current values for the number of archived bugs
and the number of open bugs? As far as I can see your graph indicates
that both values are slightly above 120000. Which, uh, doesn't appear
to make any sense at all.
According to the CGI indexes, there're 26,662 open bugs at the moment and
94,523 archived bugs, making for a total of 121,185 bugs in the database.
(The remaining bugs that get us up to #148386 were lost before we started
archiving bug logs permanently, and haven't been recovered to date)
Your graph would indicate that we passed 100,000 bugs in the archive in
early March when we haven't done that yet.

I wouldn't conclude anything yet. I don't think the data plausible.

You seem, then, to be graphing the Bug# of the most recently filed or
closed bug at the given date, which isn't really particularly informative.

Sure. I exclude fixed bugs, closed bugs and wishlist bugs. It seems
a pretty unwarranted assumption to think that the treatment of these
bugs would be so completely different as to wholly reverse a trend that
appears in the remaining bugs, which are by far the majority.
