Hello, I'm running zope 2.3.0 (Red -Hat Linux) behind apache with mod_proxy (ProxyPass) and fastcgi . All requests are satisfied successfully by Zserver , however it seems that sometimes the zope listener has to be restarted , which is not good ! What I have observed in particular, was that both apache an zope are up and working fine! But suddenly, all the requests made through browser to the zope web site, become in a blank page, the browser takes a long time to load and it shows up the not found web page. What seems to me so strange is, when this happen, both listeners are up ( netstat -l ). Then I do a restart to the zope listener and all becomes fine again ! During last week this happened four times ! I have read the zope.org mailing list and saw that other persons have problems with Zope Server, but I haven't found any suitable solutions to this problem of Zserver stability. Do you guys have any hints about the reasons of this behaviour? What should it cause this unexpected problem ? Thank you all Best regards Nuno
