在使用Spring + Scheduled Task + JPA时，我刚得到这个错误：

该应用程序非常基础，并且没有用于bean验证的自定义设置，仅使用通过Spring Boot和Hibernate验证程序自动提供的功能。例如：@ NotNull，@ NotEmpty。我在Property类上也有这些验证器，如stacktrace中所示：PersondokumentProperties。该类如下所示：
@Getter
@Setter
@Validated
@ConfigurationProperties(prefix = "freg.persondokument")
public class PersondokumentProperties {
@NotEmpty
private String identUrl;
@NotEmpty
private String apiKey;
}
但是在运行了约120万条记录的计划任务后，我得到了5个此错误。 有人知道这是已知错误还是某些配置错误？我没有用于设置休眠或bean验证的自定义代码。
似乎也同时发生。我翻转了数据库列值以重新运行，一切正常。因此，一切都在几毫秒内开始出现故障，然后一切都结束了。
编辑：当我重新部署应用程序时，似乎会发生。当旧的应用程序关闭（kubernetes）时，它将记录这些错误。关机顺序可能有问题吗？猜测
