10.1.2 When the root job terminates before its child jobs terminate
If a child job that was executed from another child job is terminated abruptly from an intermediate job by a means such as SIGKILL in UNIX or TerminateProcess in Windows, the root job might terminate without waiting for all its child jobs to terminate. For this reason, do not execute an abrupt termination of this type. For details, see 3.2.3(4) Notes about child jobs that are executed from another child job.
If this occurs, check the execution results of the related root job and its child jobs. For the child jobs other than the abruptly terminated job, the spool job directory might remain even after an attempt to delete it. Even if it was deleted, the contents of JOBLOG will have been output to the standard error output, so the log is not lost.
