I'm using IISPeek and can see that there's a single request that's hanging on a buggy page. I've fixed the bug so that others who open the page won't experience the problem, but the page is still active after almost an hour.
I'd rather not stop the whole application as there are some important processes currently running.
Via IISPeek I have the request number (9f0002008001238e) and clientIP. Could any of that be used to stop the ongoing request?
