AFAIK that message is printed when an external program, such as that
used for memory reporting, terminates. Unless you see any other ill

That sequence usually indicates that rabbit was stopped, e.g. with
rabbitmqctl stop/stop_and_halt, rabbitmq-multi stop_all, or the various
scripts in the os-specific packages.
