From time to time my zope server stop responding to http requests. The python process is running, but any request to my site doesnt produce a "200 ok" (or anything else) on the dos shell and the browser request ends with a time out.

Need a little more info: (a) What version of Zope and what version of NT (SP?) are you running? (b) Were you making requests from the machine on which the server was running? (c) What browser were you running? --Rob
