   There is lot of similar jobs and our servers may ran out of memory soon. 
   I find a field `shutoffTime` so I think it should shutdown down at 
`2019-06-10T12:15:00.000`. But it's still running. I look at the logs but 
cannot find something helpful.
   So is this a problem? If so, how to fix it?
