I would have said you also seeing 'version 3.1.' is one of the very odd
things, but then I check the bash rpm in a repo and it has 'version
3.1.' in the 3.2-32.el5 rpm.

It takes days/weeks of collecting the data via cron.daily and (I think)
having a few updates/installs happen between some of the runs.
On the boxes where I see it more, I often run the data collection script
immediately following updates.  I almost think there is some kind of rpm
housekeeping that gets done on a daily basis that could affect it, but I
can't figure out what it would be, because the rpm script in cron.daily
only dumps data (similar to what mine dumps) to /var/log/rpmpkgs... it
does not issue any rpm clean up commands. as I understand anacron, each
of the scripts should finish before anacron starts the next, so there
should not be any DB contention, between the rpm script and mine, I
would think.

At one time (in the mists of history, probably around RHEL 1|2) I
thought there was a daily rpm cleanup task, but I can't find it on Cent
5 systems.

That is my thought too.
But I don't know where rpm could be getting the different info.

I am on CentOS 5.
