Old (exiting) workers stop accepting new connections and ignores such packet or replies with 'retry' if configured. The sender assumes that the packet was lost or gets the 'retry' packet and repeats send. Hopefully, the next time old worker will already exit and the packet will be delivered to new worker. This is not ideal, but this is how it works now.
