kettle在保存作业时时候提示保存，同时资源库出现异常，打开其他操作都不行。断掉重连以后其他都正常。创建、编辑、保存其他的作业等等都没有问题，只有保存作业的时候报错。上周之前系统一切都正常的。资源库是PostgreSQL的。

保存作业时报错，图①：

主要报错显示是一个SQL语句异常，在资源库中手动执行这个sql语句也显示异常，SQL语句如下：
INSERT INTO R_JOB_ATTRIBUTE (ID_JOB_ATTRIBUTE, ID_JOB, NR, CODE, VALUE_NUM, VALUE_STR) VALUES ( '15913',  '39',  '0',  'LOG_SIZE_LIMIT',  '0',  NULL)

报错之后打开其他转换也异常了，图②：
