Redis ConnectionMultiplexer在dispose后触发多个连接失败

我们使用StackExchange.Redis ConnectionMultiplexer类，如下所示：

 private void InitializeConnection()
    {
        _logger.Info("Initializing a connection to the Redis cluster. ");
        bool isReconnectionAttempt = false;

        if (_connectionMultiplexer != null)
        {
            Debug.WriteLine("disposing " + _connectionMultiplexer.GetHashCode());
            _connectionMultiplexer.ConnectionFailed -= HandleConnectionFailedEvent;

            // test this change.....
            _connectionMultiplexer.Close();
            isReconnectionAttempt = true;
            _logger.Info("This is reconnection attempt to the Redis cluster.");
        }

        _connectionMultiplexer = ConnectionMultiplexer.Connect(_connectionString);
        _needConnect = !_connectionMultiplexer.IsConnected;
        _connectionMultiplexer.ConnectionFailed += HandleConnectionFailedEvent;

当我模拟网络问题时，ConnectionFailed事件会按预期触发。发生这种情况时，我们会尝试处理对象并创建一个新对象。但是，即使在关闭/释放前一个_connectionMultiplexer实例之后，我们仍然会收到前一个实例触发的几个ConnectionFailed事件

然而，该文档指出，当网络宕机时，我们只会收到一个ConnectionFailed事件。下一次我们遇到这样的事件是网络再次瘫痪。但这不是我所经历的。想法
