     3  Network services with heavy load will cause "connection reset" from time to
     4  time. Especially those with big payloads. When packets with sequence number
     5  out-of-window arrived k8s node, conntrack marked them as INVALID. kube-proxy
     6  will ignore them, without rewriting DNAT. The packet goes back the original
     7  pod, who doesn't recognize the packet because of the wrong source ip, end up
     8  RSTing the connection.
