Async Producer Panic

[mathiasyeremiaaryadi]

Description

My Golang service produces the data to the topic where all the data are fetched from the database. I implement the async producer, sometimes the logic works and sometimes an issue occured. The size of the data to be produced is around 1-3million. The issue seems panicking when the producer start to produce the data. I have no idea what is the error about, need some insight about how to solve it.
Here is the Go log error:

fatal error: unexpected signal during runtime execution

How to reproduce

Here are my Go producer code:

func (usecase Usecase) IngestData() *ResponseContainer {
	// Fetched data from database here ...
        listData := usecase.repository.GetData()

	// Produce data to the Kafka topic here ...
	go func() {
		for e := range usecase.kafkaProducer.Events() {
			switch ev := e.(type) {
			case *kafka.Message:
				m := ev
				if m.TopicPartition.Error != nil {
					usecase.logger.Error("Error: ", m.TopicPartition.Error.Error())
				} else {
					usecase.logger.Infof("Delivered message at [partition: %d, offset: offset: %v]", m.TopicPartition.Partition, m.TopicPartition.Offset)
				}
			case kafka.Error:
				usecase.logger.Errorf("Error: %+v", ev)
			default:
				usecase.logger.Error("Ignored event")
			}
		}
	}()

	for _, data := range listData {
                // The produce data function serializes and produce to the topic
		err = usecase.repository.ProduceData(tx, data)
		if err != nil {
			return BuildInternalErrorResponse(constants.ErrorCodeKafkaError, constants.ResponseCodeInternalError, constants.ResponseMessageKafkaError, err)
		}
	}

       usecase.kafkaProducer.Flush(10000)
       usecase.kafkaProducer.Close()

	return BuildSuccessResponse(map[string]string{"action": "All message produced"})
}

Thanks for filing this issue.
Can you tell me more about the size of the data: The size of the data to be produced is around 1-3million -> This is the per-message size in bytes, right, after serialization (as it is passed to the producer)?
