使用asyncio + Python 3.7.2，遇到一些非常奇怪的问题...
当服务器基于Linux（Ubuntu）时，我遇到了与SSL相关的错误：
SSL error in data received
protocol: <asyncio.sslproto.SSLProtocol object at 0x7f0ad36d27b8>
transport: <_SelectorSocketTransport fd=9 read=polling write=<idle, bufsize=0>>
Traceback (most recent call last):
File "/usr/local/lib/python3.7/asyncio/sslproto.py", line 526, in data_received
ssldata, appdata = self._sslpipe.feed_ssldata(data)
File "/usr/local/lib/python3.7/asyncio/sslproto.py", line 207, in feed_ssldata
self._sslobj.unwrap()
File "/usr/local/lib/python3.7/ssl.py", line 767, in unwrap
return self._sslobj.shutdown()
ssl.SSLError: [SSL: KRB5_S_INIT] application data after close notify (_ssl.c:2605)
该程序继续运行，但是由于连接似乎已关闭，导致客户端失败
来自客户端：
OSError: [Errno 107] Transport endpoint is not connected
从MacOSX提供服务器服务时不会发生这种情况...
该如何解决？
