Thanks for the reply, Peter. Yes, if you start rabbitmqctl directly via the command line then the systemd unit will not be invoked, and process will use the default limits specified by the system. If that is the way you invoked rabbitmqctl, then what you can do is modify the limits before executing the command, and see if it has any effect in mitigating the issue.
Since it is still unclear how to reproduce the issue reliably, and given that the program might have been executed without setting the limits first, I'm marking this as Incomplete again. Let us know if you come up with more details about the issue.
