   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())
        }
   }
   ```
