It looks like you have a problem with the application server: it closes
the connection down. socket.recv dutifully informs you of that.
So, the application server is what I suspect. You have not shown any
code from it, so it is hard to pinpoint your problem.

One question: why are you using a home-grown solution for passing
objects between Python applications instead of using something like
Pyro, CORBA, Twisted's perspective broker or XML-RPC? You are usually
better off *not* reinventing wheels.

Further debugging tips: take the webserver out of the question by
making controller.py be a command line script, and run it in a tight
loop. Then, put lots and lots of prints in your application server
(or maybe run it under PDB, though it might get tricky with threads)
to see where the problem is. But, again, my suggestion: go with tried
and true solutions.
