Question

I m on the developer tier why is it my flows are stuck in scheduled for a long time sometimes I don t have anything else taking up a concurrency slot

William Smith · Answer

Seems to occur if I cancel a run

William Smith · Answer

Then new runs aren t scheduled for a while

Jenny · Answer

Hi < William Smith> Thanks for the update and for mentioning that it happens when you cancel a run That helps explain the mystery of what was holding up your runs When you cancel a run it enters a cancelling state while it cancels all task runs Because cancellation is complex it can sometimes take a while Cancelling is a Running state which means it would count towards flow concurrency limits

I have an idea of how we can show this better on the UI now so thanks again for raising it

William Smith · Answer

Ah OK makes sense thanks for getting back to me

William Smith · Answer

I do find this still happens even though the state has been set to cancelled though
