[Zope] Zope Dies Mysteriously After A Few Days. How Do I Investigate Zope's Death?

My new goodbyejim.com site runs Zope 2.6 and Python 2.1 on Redhat 7.3 It uses Squishdot. Ever since I fired the site up a few weeks ago it has been dying mysteriously every few days. When I look in the var/Z2.log file there is no evidence that anything went wrong. If I then run the stop script it says that Zope is not running. I can then always restart Zope using the start script without problem. If I run the uptime Unix command I find that the Linux box itself has been running without problem. What could be causing my Zope to die? How do I investigate it? __________________________________ Do you Yahoo!? New Yahoo! Photos - easier uploading and sharing. http://photos.yahoo.com/
