Adjusted frame length exceeds 4096: 25346 - discarded

服务器 定义解码器 super(4096, 0, 2, 0, 0);

客户端
正常情况 ：
       String host = "127.0.0.1";
        int port = 8586;
        Socket client = new Socket(host, port);
        DataOutputStream dos = new DataOutputStream(client.getOutputStream());
       
        while (!client.isClosed()){
            dos.writeShort(2); //输出总长度
            dos.writeShort(0x0001); //命令
            dos.flush();
            Thread.sleep(3000);
        }
        dos.close();
        client.close();

粘包情况:
        String host = "127.0.0.1";
        int port = 8586;
        Socket client = new Socket(host, port);
        DataOutputStream dos = new DataOutputStream(client.getOutputStream());
       
        while (!client.isClosed()){
            dos.writeShort(3); //输出总长度
            dos.writeShort(0x0001); //命令
            dos.writeShort(5); //命令
            dos.flush();
            Thread.sleep(3000);
        }
        dos.close();
        client.close();
这样第一次发是没有问题的，第二次服务器就报错了，以下是错误信息:
io.netty.handler.codec.TooLongFrameException: Adjusted frame length exceeds 4096: 25346 - discarded
