There's a bunch of maintenance stuff that happens regularly that's on that list... FCSTDV (stationkeepng burns), FCSTMX (scheduled maintenance, like switching to a different atomic clock or the like), that sort of thing. There's a lot of recent UNUNOREF on the agi.com link in this thread's grandparent, which is basically "it broke and came back before we could send out a note". If you look closely at that list, though, you'll see that almost all of the recent events are a single satellite -- PRN18. I have no idea what's wrong with it (and AFAIK there's no way for the public to get the details), but it's been going unhealthy for ~2 minutes at a time for months now. (I'm guessing they keep it live because either don't have another satellite positioned so they can put it into that slot easily, or because they don't consider whatever is wrong with it to be a huge problem.)
