And this is immediately followed by the standard request
You didn't quote the server response to the first request, but it sounds like your server is feeding back a corrected url to googlebot. Depending on what that response is, exactly, you may be in good shape. But there's a chance the server is not giving the right response and then googlebot will never stop asking for the single slash.
The IP address you quoted is in the range owned by Google, so this is probably not a hack attempt by someone faking a googlebot user agent.
