Is it possible to kill a running metaflow given its id - I seem to have one process running as shown in the UI - it was started locally and I even restarted machine but process/flow still appears running in AWS UI. Thanks!

It is probable that the task is not running even though the UI says that it is. If a task fails without having time to tell the UI it will remain visible for 1 day (depending on your config) without sending a heartbeat

thanks will have a look tomorrow.
