# Queued Duration

### Condition

Query is stuck in `QUEUED` status. It is usually caused by having too many queries trying to run in parallel on the same warehouse at the same time.

### How to fix

* Consider using multi-cluster warehouse.
* Move workload to another warehouse.
* Add concurrency limits for ETL and reporting jobs.

One Snowflake warehouse instance can normally run up to 8 small queries in parallel with default settings. This amount can be increased.

### Example

```
    QueuedDurationCondition(
        notice_duration=60 * 30,  # query was in queue for 30 minutes
    ),
```

### Specific arguments

None. Only [standard duration arguments](https://docs.snowkill.net/condition) are applied for this checker.
