coap协议数据丢失

EMQX 性能问题
1

emqx5.7版本
使用coap协议无连接模式
一个客户端订阅test主题。一个客户端发送主题消息
大概代码如下

for (int i = 0; i < 300; i++) {
            CoapClient client = new CoapClient("coap://172.30.13.222:5683/ps/test");
            Map<String, Object> map = new HashMap<>();
            map.put("int", i);
            map.put("txt", UUID.randomUUID().toString());
            map.put("clientId", "f7005374577147c3b1c4730475958a72");
            String message = JSONObject.toJSONString(map);
            Request request = Request.newPost();
            request.setPayload(message.getBytes());
            request.getOptions().setContentFormat(MediaTypeRegistry.TEXT_PLAIN);
            // 发送POST请求
            CoapResponse response = client.advanced(request);
            // 检查响应状态
            if (response != null) {
                System.out.println("Message published successfully: " + response.getResponseText());
            } else {
                System.err.println("Failed to publish message.");
            }
            System.out.println("i is " + i);
            Thread.sleep(500);
        }

客户端向test主题每0,。5秒发送一条消息
两一个客户端接收消息中间有一半消息丢失，大概是一分钟有消息，一分钟没有消息
emqx的日志是正常的，客户端接收到消息的情况如下

请问是什么原因导致大概每一分钟就有消息丢失，过一分钟就是正常的，是需要添加什么配置吗？

2

感谢反馈，我们安排人进行排查下，如果是bug我们尽快修复

3

希望排查原因，如果是需要修改什么配置，麻烦告诉我一下

4

linux环境centos7.4
emqx版本是5.7.2
coap是无连接模式
java客户端订阅主题，关键代码如下

 CoapClient client = new CoapClient("coap://172.30.13.222:5683/ps/test");
        // 设置回调处理器
        CoapObserveRelation observe = client.observeAndWait(new CoapHandler() {
            @Override
            public void onLoad(CoapResponse response) {
                System.out.println("Received message: " + response.getResponseText());
            }

            @Override
            public void onError() {
                System.err.println("Error occurred while observing the topic.");
            }
        });

另一个客户端每隔0.5秒发送消息
关键代码如下

CoapClient client = new CoapClient("coap://172.30.13.222:5683/ps/test");
        for (int i = 0; i < 300; i++) {
            Request request = Request.newPost();
            Map<String, Object> map = new HashMap<>();
            map.put("number", i);
            String message = JSONObject.toJSONString(map);
            request.setPayload(message.getBytes());
            request.getOptions().setContentFormat(MediaTypeRegistry.TEXT_PLAIN);
            // 发送POST请求
            Thread.sleep(500);
            client.advanced(request);
        }

订阅者每隔一段时间就接收不到消息
订阅端关键日志如下：

也就是从第17条消息接收到后面就没有消息，过了一个1分钟，后面的消息就可以接收到，然后又过了大概一分钟又不能接收到消息
请问是不是哪里需要添加配置，这个仅仅是coap协议基本使用场景

麻烦提供一个 emqx 的日志

由于 UDP 是非流式的，其没有持续连接的保障，在接收方掉线后，既使重新上线，也会被识别为新的会话，因此之前的消息会出现收不到的情况。
你这里需要使用「连接模式」，连接模式会尝试对 UDP 报文进行预解析，然后使用 ClientID 将 UDP 管道和会话绑定。
