软件版本：Loadrunner11 path3

脚本代码：
Action()
{
    flex_rtmp_connect(
        "connect_step0",
        "Host=192.168.2.103:1935",
        "ConnectionID=6",

        LAST);

    flex_rtmp_receive_stream(

        LAST);

    flex_rtmp_disconnect(
        "disconnect_step0",
        "ConnectionID=6",
        LAST);
}

问题：
flex_rtmp_connect和flex_rtmp_receive_stream两个函数的"ConnectionID"参数是一样的，但为什么我在flex_rtmp_connect函数里填的地址是"192.168.2.103:1935"，可是回放日志里看到，flex_rtmp_receive_stream这个函数却是从"192.168.2.101:1057"拿数据？
