Topic creation on restart
Some times during a rolling restart, I see lots of these messages during
the restart (these happened in the logs of the 2nd server in the cluster to
restart (broker 11), after having restarted started, and during the time
the 3rd node (broker 9) is doing a controlled shutdown before stopping).

Is it creating new topics (it shouldn't have been!).  Or is it moving
topics around, or what?
