[Zope] Cache flipping?

I'm getting many of these in my event.log 2005-03-15T10:17:56 INFO(0) ZEC:1-None-1 flipping cache files. new current = 1 The goes down, every few days with no errors, other than the one above. In one instance the site went down after an error in a page template. This code shows in the event log just prior to the site going down. <p tal:repeat="photo container/objectValues"> <img tal:replace="structure photo"> <span tal:replace="photo/title">title</span> <span tal:replace="photo/getDescription">Description</span> </p> It seems improbable that the site would go down because of an error in a page template.
