I unfortunately do not have a way to reproduce this. This indeed happened in a large-ish production env with lots of clients. It's the first time I saw this.
One thing I'm wondering, if rabbit were started with
$ sudo rabbitmqctl start_app
the systemd unit file probably would not go into effect, and the default limits would apply, right?
It's possible that by way of troubleshooting this rabbit instance had been started up via rabbitmqctl (I don't know for sure though).
