处理后，Redis ConnectionMultiplexer触发多个ConnectionFailed

Question

我们正在使用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，会按预期触发ConnectionFailed事件。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，即使在前一个_connectionMultiplexer实例被关闭/处理之后，我们仍然会获得前一个实例触发的几个ConnectionFailed事件。

但是，该文档表明，当网络出现故障时，我们只会收到一个ConnectionFailed事件。下次我们得到这样的事件时，网络再次出现故障。但这不是我所经历的。想法？
