I'd start out by adding a try/catch block around the code.  From what I 
see, the program could be failing with a simple connection failure, 
which the code you showed doesn't handle.

Also, make sure the output is flushed, otherwise you might get the wrong 
information.  Writing an endl at the end of each output entry should do 
the trick.
