[Zope] Cache flipping?

[Darian V Schramm]

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.
