I believe that dwh was killed and not stopped correctly by service stop, and therefore did not exit cleanly.
This is why it did not send  an exit message to the log and did not update the engine that dwh is not running.

The log, posted earlier in this thread, seems to show it's actually running:

The end of it looked like this:

>From this, I understood that:
1. Many months ago, either there was some problem (e.g. dwhd could not
connect to engine db, or not see updates there, or whatever) or simply
there was no new data (engine was down, or simply nothing changed (is
this possible?)).
2. Then things became ok for several months (or at least, nothing
caused dwhd to say otherwise)
3. Then dwhd was restarted, perhaps for an upgrade, and still no new errors.

Fernando: Do you still only get empty reports?
