Just to be clear, while I used RPT as a way of mounting the attack, I think it is not a requirement.

A malicious client can repeatedly migrate to a new address, initiating the use of new CID pairs, at the same time intentionally not acknowledging packets containing RETIRE_CONNECTION_ID frames sent from the server. If the client does that, the number of CIDs that the server has to track for retirement increases as time goes.
