I forgot to mention:

The ProxyPass works ok. After some work in the management folder, Apache sends me the error message:

If the proxy rules are all working fine to start with, then there shouldn't be any reason for them to suddenly stop working.

"The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /. Reason: Could not connect to remote machine: Connection refused"

This is saying that it is trying to proxy your request, but the backend server is not responding (ie. the zope server is not responding).

When I reboot the server, everything goes ok again.

This further strengthens the case that this problem is not related to the ProxyPass at all, rather to do with what you are doing to your zope server. It works. You do some things. It stops working. You reset the server. It works. Throughout all of that, ProxyPass is proxying your requests, so that is not your problem.
