Hi, I've noticed that the scheduler service sometimes stops scheduling new runs. Nothing is logged by the towel container, the last message is a standard "Sleeping for 300.0 seconds". Restarting the services resolves the issue. I have a slight suspicion that this is occurring when one flow run overruns past the start time of the next run. But I see no relevant GH issues in either the

prefect

or

server

projects, so wondered if maybe I'm just misunderstanding something about how it's supposed to work. Is anyone aware of this already?

Hey @Chris Bowdon, I haven’t seen this issue mentioned recently, but I would definitely recommend upgrading to the latest version of Prefect to see if this persists. If the behavior you’re observing continues, we can definitely triage here or in a GH issue to narrow the source.

Thanks @Kyle Moon-Wright! I'll see how it goes.

Awesome! And don’t forget about the folks on #prefect-server, who might have more experience with Server related troubleshooting.
