# Job Reason Codes

These reason codes can be used to identify why a pending job has not yet been started by the scheduler. There may be multiple reasons why a job cannot start, in which case only the reason that was encountered by the attempted scheduling method will be displayed. Refer to the Scheduling Configuration Guide for more details.

## Common Reasons

- AssocGrp* — The job's association has reached an aggregate limit.
- AssocMax* — A portion of the job request exceeds a maximum limit (e.g., PerJob, PerNode) for the requested association.
- BeginTime — The job's earliest start time has not yet been reached.
- Dependency — This job has a dependency on another job that has not been satisfied.
- Max*PerAccount — A portion of the job request exceeds the per-Account limit on the job's QOS.
- Priority — One of more higher priority jobs exist for the partition associated with the job or for the advanced reservation.
- QOSGrp* — The job's QOS has reached an aggregate limit.
- QOSMax* — A portion of the job request exceeds a maximum limit (e.g., PerJob, PerNode) for the requested QOS.
- Resources — The resources requested by the job are not available (e.g., already used by other jobs).
