I have an unhealthy work queue that shows 5 flows with Running status. However, those flows are actually not running. The server crashed with out of memory error. Upon restart, they're still there. How do I delete them and get the work queue back to a healthy status?

Hello Thuy, thank you for raising this. Crashes like these will be handled more gracefully when the flow run cancellation and 2.0 zombie killer features are released. In the interim, you can now delete flow runs directly from the UI on the flow run page.
