What is probably happening is that a config poll is going to a router (daily
config polls are on a 24 hour timer). When the arp cache is received, there
must be a new device in it that matches discovery seed file settings.
Devices in the router arp cache I would assume are added only when they meet
the discovery criteria unless new node discovery is turned on.

I get things discovered in the wee hours
of the night too.  I don't know, but it
wouldn't surprise me to find that NetView
gauges how much (if any) discovery to do
depending on the speed of status ping responses.
That is, if they are slow, don't do discovery cause
things are busy.  If they are fast (during the
night), do discovery cause things are
idle.
