The Pi has now been running for two weeks since the last reboot. In addition to switching from using local sqlite databases (for everything except weewx) to the use of a mariadb database on my NAS, I removed one database-accessing service which was no longer needed (it assembled data to be displayed by an app on my main Windows machine - the app now takes it directly from the networked database). I have pasted a summary of top output since the reboot below. The relatively transient drops in free swap space seem to reflect the after-effects of periods of reasonably heavy interactive usage of the Pi, but otherwise everything seems to be working well.
