I got this log by setting NSURLRequest to an invalid URL. My application should show UIAlertView when it causes a server-side error, so I asked our system administrator to delete our entire site so that I could see what was happening. He rejected my request, so I typed in random letters and put .com at the end of the request URL.
It turns out that we have an internal test server that does not seem to be accessible from my WiFi connection, so when I changed the URL to it, the log stopped.
