"job has been notified to stop, but failed to do so immediately"
*Cause: The job specified in the stop_job command
cannot be stopped immediately(because it is rolling back or blocked
on a network operation), but it has been notified to stop. This
means it will be stopped as soon as possible after its current
uninterruptable operation is done.
*Action: No action is required for the job to be stopped, but calling
stop_job with force (if you have the privilege)
may cause the job to be stopped sooner.
