Yes, there is a timeout value buried in ZServer.  Go look in the file
/usr/share/zope/ZServer/HTTPServer.py, class zhttp_channel.
There is a class variable 'zombie_timeout', set to 100 minutes.  Also
look in /usr/share/zope/ZServer/medusa/http_server.py for 'zombie'
code, *both* in the  http_channel class and status_handler class.
In the medua/http_server.py class, that timeout is *** 30 minutes ***.

When a ZServer channel has been in existence for that long, it is automatically
closed, in the method kill_zombies() of that class.  This may be your problem.
