Answer 1

I had the same problem when running CherryPy 3.2.2 on my Win7 PC with Python 3.3 The server would start normally and then would crash in about a couple of minutes.

I've applied the patch from CherryPy 3.2.3 laurasia mentioned. But it didn't help.

So I had to comment out the lines raising the error at the very end of python\Lib\site-packages\cherrypy\process\servers.py to prevent the server from dying:

...
#    if host == client_host(host):
#        raise IOError("Port %r not bound on %r" % (port, host))
...
