   The issue tracker is **ONLY** used for the go client (feature request of RocketMQ need to follow [RIP process](https://github.com/apache/rocketmq/wiki/RocketMQ-Improvement-Proposal)). Keep in mind, please check whether there is an existing same report before your raise a new one.
   
   Alternately (especially if your communication is not a bug report), you can send mail to our [mailing lists](http://rocketmq.apache.org/about/contact/). We welcome any friendly suggestions, bug fixes, collaboration, and other improvements.
   
   Please ensure that your bug report is clear and that it is complete. Otherwise, we may be unable to understand it or to reproduce it, either of which would prevent us from fixing the bug. We strongly recommend the report(bug report or feature request) could include some hints as to the following:
   
   **BUG REPORT**  
   1. Please describe the issue you observed:
   
   ```
   for i := 0; i <= 100; i++ {
   		opts := []consumer.Option{
   			consumer.WithGroupName(normalGroup),
   			consumer.WithInstance(namespace),
   			consumer.WithMaxReconsumeTimes(5),               //消息最大重试消费次数
   			consumer.WithPullBatchSize(1),                   //批量拉取时最大拉取数
   			consumer.WithConsumeMessageBatchMaxSize(int(1)), //批量消费最大推送数量
   			consumer.WithNamespace(namespace),
   			consumer.WithNsResolver(primitive.NewPassthroughResolver([]string{tcpEp})),
   			consumer.WithCredentials(primitive.Credentials{
   				AccessKey: accessKey,
   				SecretKey: secretKey,
   			}),
   		}
   
   		c, err := rocketMQ.NewPushConsumer(
   			opts...,
   		)
   		if err != nil {
   			log.Fatalln("rocketMQ.NewPushConsumer err: ", err)
   		}
   
   		selector := consumer.MessageSelector{Type: consumer.TAG, Expression: normalTag}
   		if err = c.Subscribe(topic, selector, normalMsgHandler()); err != nil {
   			log.Fatalln("rocketMQ.Subscribe err: ", err)
   		}
   
   		if err = c.Start(); err != nil {
   			log.Println("rocketMQ.Start err: ", err)
   			continue
   		}
   		if err = c.Shutdown(); err != nil {
   			log.Fatalln("rocketMQ.Shutdown err: ", err)
   		}
   	}
   ```
   using pprof can see the leak of goroutine.
