func (p *Process) killProcess(sig os.Signal) error {
	select {
	case <-p.cmdReadyCh:
		p.logger.Debugf("[%s] start to kill process", p.getTxId())
		if p.cmd == nil {
			return errors.New("process cmd is nil")
		}

		if err := p.cmd.Process.Signal(sig); err != nil {
			return fmt.Errorf("failed to kill process, %v", err)
		}

		return nil
	default:
		p.logger.Warnf("[%s] process is not ready", p.getTxId())
