Unclean kafka shutdown
I've noticed that kafka frequently fails to shut down completely when
running the shutdown script. After executing kafka-server-stop.sh, it
outputs this and does not return to the prompt. Is this anything to be
concerned about? An addition kill command will force it down.

Dunno if this is relevant, but if you're spinning down a broker handling
live data, you probably want to check this page out:

Just curious about, whether the memory allocated is released or not.
