    Shunning not works on network cut off

    László Süt? Newbie

      There is two nodes: A, B. They are in one group, then we cut off the network cable of A then we notice from the log that two of them are in a single group. After plug in back the network cable into the A then they merged together but none of them get the actual state of the other.

      Our configuration:
      <UDP send_on_all_interfaces="true" receive_on_all_interfaces="true" mcast_addr="228.1.2.3" mcast_port="48866"
      ip_ttl="64" ip_mcast="true"
      mcast_send_buf_size="150000" mcast_recv_buf_size="80000"
      ucast_send_buf_size="150000" ucast_recv_buf_size="80000"
      use_incoming_packet_handler="false" use_outgoing_packet_handler="false"
      loopback="false"/>
      <PING timeout="2000" num_initial_members="3"
