My a priori guess, knowing that we don't directly use any python programs is that it's either some Nagios plugin or some Munin plugin (there are a few that are written in python) that's actually causing the files to get updated. There's nothing else that should be running as root on these systems. If I get a moment, I can check which plugins meet those criteria and try disabling them. -GAWollman
