   Thanks @lspgn, Unfortunately, I can't  reproduce the issue in my local.
   
   Use code as follows:
   
   ```
   package main
   
   import (
   	"context"
   	"fmt"
   
   	log "github.com/apache/pulsar/pulsar-client-go/logutil"
   	"github.com/apache/pulsar/pulsar-client-go/pulsar"
   )
   
   func main() {
   	client, err := pulsar.NewClient(pulsar.ClientOptions{
   		URL:       "pulsar://localhost:6650",
   		IOThreads: 5,
   	})
   
   	if err != nil {
   		log.Fatal(err)
   	}
   
   	defer client.Close()
   
   	producer, err := client.CreateProducer(pulsar.ProducerOptions{
   		Topic: "topic-1",
   	})
   	if err != nil {
   		log.Fatal(err)
   	}
   
   	defer producer.Close()
   
   	ctx := context.Background()
   
   	for i := 0; i < 10000000; i++ {
   		msg := pulsar.ProducerMessage{
   			Payload: []byte(fmt.Sprintf("hello-%d", i)),
   		}
   		msgID, err := producer.SendAndGetMsgID(ctx, msg)
   
   		if err != nil {
   			log.Fatal(err)
   		}
   		fmt.Printf("the %s successfully published with id %v\n", string(msg.Payload), msgID.Serialize())
   	}
   }
   ```
   
   The broker version:
   
   - 2.4.1
   - 2.4.2
   - 2.5.0
   
   The client version:
   
   -  github.com/apache/pulsar/pulsar-client-go v0.0.0-20191214024039-b52449a6604c
   
   Can you provide a stable reproduce code?
