If I recall correctly, a source is no longer reported when it has
performed shut_down_thresh connection attempts (default: 100).
Instead Bro then just generates a ScanSummary after 1 day or at
termination, whatever comes first.

It will be reset; by default Bro does not carry state across
restarts (it may though by declaring things as &persistent).


P.S.: You wrote, you're checkpointing every 3 hours. Do you do this
primarily to avoid running out of memory? If yes: in newer
(development) versions, we've greatly improved the state management,
so this may become unneccesarry eventually.
