Step status To be Canceled in Workflow Queue

Hi everyone,

We have some task steps in our workflow queue that have been canceled, but rather than actually being canceled, they have the status "To be canceled". All of these tasks are running on the same FTS server; canceled steps on the other FTS cancel immediately. Do we simply have to wait for garbage collection to run on the server, or is there some other way to forcibly clear the queue of these tasks?
