I was in the process of making a change to an existing Deployed Event Policy when I selected Edit Policy the window froze. I waited 10 minutes then closed the window, then closed the SOI console. When I reopened it and select EDit Policy again I get a pop up window that specifies. 'Cannot obtain exclusive lock required to change Event policy. The resource is already locked by user.'
Program was closed before it could release the lock.
Login to UI Debug page
