Question

我在c＃控制台应用程序中遇到内存泄漏问题，我对它造成的影响有点不知所措。

我在不同阶段对应用程序进行了转储，以比较堆的更改方式。我注意到有许多固定的对象引用和相当多的ActiveMq对象。下面是我的ActiveMq消费者，制作人和连接。我正在使用最新的Apache.NMS.ActiveMQ nuget包。

    public ActiveMqClient(ILogger logger, IAdaptorConfig config)
    {
        try
        {
            _config = config;
            _logger = logger;

            var connectionFactory = new ConnectionFactory(_config.ConnectionString);
            _connection = connectionFactory.CreateConnection(_config.Username, _config.Password);
            _connection.RequestTimeout = TimeSpan.FromSeconds(3);
            _session = _connection.CreateSession();
            _connection.Start();
            _logger.Info(string.Format("Successfully created a connection to ActiveMq with client id:{0}, timeout {1} and prefetch policy {2}", _connection.ClientId, _connection.RequestTimeout, connectionFactory.PrefetchPolicy.QueuePrefetch));
        }
        catch (Exception e)
        {
            _logger.Error(string.Format("Failed to create connection to messaging service using connection string {0}, Exception: {1}", _config.ConnectionString), e.Message);
        }
    }

    public void Subscribe()
    {
        try
        {
            var dest = _session.GetDestination(_config.InQueue);
            _consumer = _session.CreateConsumer(dest);
            _consumer.Listener += OnMessage;
            _logger.Info(string.Format("Subscribed to activeMQ queue {0}", _config.InQueue));
        }
        catch (Exception ex)
        {
            _logger.Error(string.Format("Failed to subscribe to {1} . ex: {0}", ex.Message, _config.InQueue));
        }
    }

    public void SendMessage(string message)
    {
        try
        {
            using (var dest = _session.GetDestination(_config.OutQueue))
            using (var producer = _session.CreateProducer(dest))
            {
                producer.RequestTimeout = TimeSpan.FromSeconds(3);
                var request = GetSession().CreateXmlMessage(message);
                request.Text = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>" + message;
                producer.Send(request);
                _logger.Info(string.Format("Created new producer and sending message to {0}", _config.OutQueue));
            }
        }
        catch (Exception e)
        {
            _logger.Error("Problem sending message", e);
        }
    }

问题可能完全来自应用程序的另一部分，但此时似乎最有可能是activeMq。

我想知道是否有人能发现任何可能导致代码中内存泄漏的内容？如果我能提供更多可以提供帮助的信息，请告诉我们。
