there is a very few information about a Bulk action that is running for very long time, I guess for more than 24 hours, and there is no a way to know what is doing and how to stop it or killed
have you checked the control panel to see the settings to kill or suspend it, or goto the administrative screen, otherwise you have to delete single information.
4 years later this is still a problem. I'm having the issue now. It stopped working but is still running and I don't have the option to click on the "stop" button. It appears to be greyed out.
Can you check it now. There was a task update failure we have cleared it now.
It's still happening. I see that the job was stopped, when I tried to run the same exact task again, the issue continued.
