We have on several occasions had marketing efforts or exports or saving static selections run for up to 13 hours before they finally fail. Once they start, there is no way to stop them and they tie up system resources for every other process that is running, impairing performance for all of our users. My only option is to contact your support team and ask them to terminate the process, which can also take a lot of time and wastes your resources as well as mine.

I would like to see an option under Administration > Business Processes > History tab where I could cancel an running process in the same way that I can cancel a query while I am running it. This would give us the ability to handle the problem as soon as it becomes apparent without wasting your resources.
