When an endpoint sends a RETIRE_CONNECTION_ID frame carrying a connection ID that has been active until that point, that endpoint is expected to open room for accepting a new connection ID.

That means that if the peer does not acknowledge the packets that contains RETIRE_CONNECTION_ID frame, but keeps on sending NEW_CONNECTION_ID frames with increasing values in the Retire Prior To field, the number of unacknowledged RETIRE_CONNECTION_ID frames (or to be precise, the number of unacked retiring connection IDs) keeps on increasing.
