It alway throw me an error saying that “too many activity sessions.” But I have closed all the related windows. Can anyone let me know what is happening?
I personally have never seen this message, so I’m not sure about the answer, but I guess closing the window does not end the session instantly (you should click “Manage Sessions” button).
Or alternatively, if you go to Menu “Runtime” > “Manage Sessions”, you should see a list of active sessions - terminate those you don’t need.
Let us know how you solved the issue.
