[Zope] a new zope dying

My new Zope server at www.feinsteinhs.com seems to stop working a few times a day for no apparent reason. I compiled 2.3.3 and Python 1.52 on my DebianPPC system. I do get that "Problem(100) Unhandled Event" error, I think when it first serves a page--can't find an explanation of that. This is also the first time I've had to roll my own init script. Could that be the problem? Should the init script just be starting the process with the standard "start" command in my Zope directory? I couldn't get the zopectl product to work, because I couldn't figure out the config from the docs, but it seemed like that might be helpful. Any suggestions? Thanks! --Tom Hoffman
