This makes no sense to me - TG2.1 has nothing todo with Cherrypy. >From what I gather, the problem seems to occur if the generator fails. I suggest you put a proxy like tcpmon in between your browser & webapp, and see what goes over the wire. Also, what happens if you return the data at once, and what happens if you put exception-catching code around the generator, and dump whatever exception is created to some logfile.
