I have opened up the 3.4GB file with Python and started doing file.readline() on it. The first few lines of the file are:

Service not available. Using thread. Loading database... SMTP Listener on port 25 is proxying mail.utexas.edu:25 Listener on port 110 is proxying mail.utexas.edu:110 User interface url is http://localhost:8880/ warning: unhandled exception warning: unhandled exception

Are you positive that you're using the 1.0.4 binary? The "warning: unhandled exception" message is printed by asyncore (and nothing else, AFAIK), but the function that prints it doesn't get called with Python 2.3 (with which 1.0.4 is built). I can't duplicate this with Python 2.3 no matter what I do with my network connection. If you do have time to try and track this down, the best way (especially since you have Python install already) would be to run from source (with Python 2.3, ideally) and modify Lib/asyncore.py to stop when the "unhanded exception" message is printed. That way we would be able to tell who is calling the function, and verify that it is asyncore and not a matching error from somewhere else. =Tony.Meyer -- Please always include the list (spambayes at python.org) in your replies (reply-all), and please don't send me personal mail about SpamBayes. http://www.massey.ac.nz/~tameyer/writing/reply_all.html explains this.
