The Nun.Me.Shu web site is hosted in a more or less experimental environment that is shared by other web sites that employ and test new technologies. Occasionaly this may manifest itself in performance problems. Except for the front page, all pages on this site are transformed real-time from XML into HTML (or served from cache). This is done by a local instance of Cocoon2, a Java servlet. The servlet container, Tomcat, is shared with other sites though. Performance of Tomcat therefore depends on activities on those other sites; heavy activity may lead to problems processing pages on the Nun.Me.Shu site. Unless the servlet engine has been stopped completely, waiting a few seconds and reloading the page may solve the current problem.

Possible causes of the current problem (starting with the most likely one):

• Cocoon2 is supposed to process a page request, but the web server, Apache, takes over and tries to serve the page. In many cases on the Nun.Me.Shu site, a page does not exist physically, but is generated on-the-fly. If Apache tries to serve a page like this it naturally can not find it. This is especially the case when selecting the "view-XML-source" button on any page.
• The page does not exist. You have either discovered a broken link on one of our pages, or, if you typed a URL by hand, you may have made a typo.
• Other sites are being deployed or tested, affecting overall performance of the servlet engine (Tomcat).
