Pflows Continue to Run after Cancelling

Hi All,

I have some flows that I am testing by launching via Designer with the "Run on Server" checkbox checked. I'm trying to cancel the flow by going into Pflow Admin, finding the WorkUnit and clicking the "Cancel" button. The status changes to "8-Cancellation Completed" but the flow continues to run (or, at least, the wflog file continues to grow).

If it matters, I'm trying to cancel in the "middle" of a sql node. The node returns far more records than I expected, so I wanted to cancel and try again.

Is there some other way to "kill" a running flow so that it actually stops?

Thanks!
