cserwen opened a new issue #813: URL: https://github.com/apache/rocketmq-externals/issues/813
The issue tracker is **ONLY** used for bug report and feature request. Any question or RocketMQ proposal please use our [mailing lists](http://rocketmq.apache.org/about/contact/). **BUG REPORT** 1. Please describe the issue you observed: The number of long connections on the MQTT server is higher than expected, increasing by 200~400 at the same time or at the highest point every day. After restarting the MQTT service, the number of connections returns to normal, and there are many failed connections on the server side that have not been released. 2. Please tell us about your environment: Linux 3. Other information (e.g. detailed explanation, logs, related issues, suggestions how to fix, etc): Due to factors such as network cutting and client crashes, when one party exits abnormally during a long connection, the other party will not be able to perceive that the long connection has failed. In order to ensure the validity of the long connection, to detect whether the client is disconnected abnormally in time, a heartbeat is required for detection. -- This is an automated message from the Apache Git Service.
