i have 4 simple flows i ran periodically every hour and for some reason it looks like i am running more than 20k tasks, are clock registrations being multiplied in some way?

I’m not getting what you mean by clock registrations here. Could you elaborate? Do you mean you added multiple <https://docs.prefect.io/core/concepts/schedules.html#clocks|clocks> to the schedule?

no i have a dlow in which i simply create an interval clock

i was wondering, when i bump the version and re-register

```def _create_clock(env_name: str, tables: list[str], optimized_format: str) -&gt; Clock:
    return IntervalClock(
        interval=OPTIMIZED_TABLE_CREATION_INTERVAL,
        parameter_defaults={
            "env_name": env_name,
            "tables": tables,
            "optimized_format": optimized_format,
        },
    )```

this is passed to:
```clocks = _create_clocks(...)
Schedule(clocks=clocks)```


The clock/schedule in general will not be tied to the task run count. It would be tied to the Flow run count. I think you could see in the dashboard if you have more flow runs than you are expecting. To answer though, the old version of the Flow is archived when you re-register and won’t be used

yeah but i would assume that if i have a 1 per 3 hours run for a flow

that would mean i would have in general 4*10 task runs a day

not 20k , so i was wondering if i have a bug and that the old clocks are still set somewhere

looking at the run logs it looks like i dont have that many , which is weird

You can check the schedule tab of the Flow to verify, but no previous Flow versions can’t be run by Prefect Cloud. You would get an error if it were attempted
