.Net Core 3.1 app)TCP服务器收到一个异常的字节流

我用.net core 3.1开发了一个服务器app，在window7编译好，直接放置到阿里云linux服务器下运行，用SocketAsyncEventArgs处理网络并发,但是服务器运行了一段时间后，服务器收到一条异常的字节流，

完整的字节流是：

{0,0,0,164,255,83,77,66,114,0,0,0,0,8,1,64,0,0,0,0,0,0,0,0,0,0,0,0,0,0,64,6,0,0,1,0,0,129,0,2,80,67,32,78,69,84,87,79,82,75,32,80,82,79,71,82,65,77,32,49,46,48,0,2,77,73,67,82,79,83,79,70,84,32,78,69,84,87,79,82,75,83,32,49,46,48,51,0,2,77,73,67,82,79,83,79,70,84,32,78,69,84,87,79,82,75,83,32,51,46,48,0,2,76,65,78,77,65,78,49,46,48,0,2,76,77,49,46,50,88,48,48,50,0,2,83,97,109,98,97,0,2,78,84,32,76,65,78,77,65,78,32,49,46,48,0,2,78,84,32,76,77,32,48,46,49,50,0}

我试着用ASCII解析它，结果是:

{\0\0\0??SMBr\0\0\0\0\b\u0001@\0\0\0\0\0\0\0\0\0\0\0\0\0\0@\u0006\0\0\u0001\0\0?\0\u0002
PC NETWORK PROGRAM 1.0\0\u0002
MICROSOFT NETWORKS 1.03\0\u0002

像是一些软件或硬件的版本信息

有大神遇到过这个问题吗?
