Start with the SchedLog -- Matched + Idle usually indicates the scheduler is having issues completing the claim process with the node so it can't send the job over. If the SchedLog says the claim was acknowledged and a shadow was spawned successfully for the job, go to the ShadowLog file and see if you can find information about the shadow that was spawned for the job.
