Received an alert message that I got in My Steelport Emulator tool

Hi, I use My Steelport Emulator. For some reason, I got something. Here's how it looked:
Code:

Received an alert: CloseNotify

Can someone explain what is that Received an alert thing? And also that CloseNotify thing?
Because I don't know what that is. I don't even work at Volition! So I don't know what that is. So again, can someone explain what is this?
