What logs 'unknown [stream] error code...' ?

One of the functions in my application sends a request to each of the user's Safari bookmarks, logs the first response, then closes the connection. While it's waiting for a response, it opens connections to other bookmarks, throttled to have no more than 64 connections open simultaneously. In my code, this is all done in one thread, thanks, I suppose, to the magic of NSURLConnection.

Although I've been shipping this for 3 years and have had almost no trouble with this function, yesterday a user reported that my app crashed twice during while executing it. He retried today, and it did not crash, but my trouble-zipping tool sucked these odd messages out of today's console log. These messages are not generated by my code. Does anyone know where these come from and what they might mean?
