+1, there is no exact match, but 2502 is the closest match that also indicates that the connection will be closed.

Admittedly, looking at this, our 2502 doesn't seem to be overly suitable either: 2502 "Session limit exceeded; server closing connection" This response code MUST be returned when a server receives a <login> command and the command cannot be completed because the client has exceeded a system-defined limit on the number of sessions that the client can establish. It might be possible to establish a session by ending existing unused sessions and closing inactive connections. (as this clearly refers to the number of open registry connections only). I guess we interpreted "Session limit exceeded" in a liberal fashion, in the sense that exceeding a rate limit means exceeding a limit *of* this session, not the limit to the number of sessions. Anyway, as the goal is to stop the client from further hitting the server, closing the session (as opposed to let subsequent commands fail, allowing the load on the server to continue) is IMHO a good way to react, and in that case this seems to be the most suitable response code.
