How an unauthenticated TLS half-open flood pins rippled's memory and crashes it under low file-descriptor limits
rippled's inbound TLS listeners on the peer port (51235) and the RPC-HTTPS port (5006) accept a partial TLS handshake with no deadline and no per-IP half-open cap, so a single source IP can pin server memory indefinitely and, at a default file-descriptor limit, crash the process.
