[Zope] Zope hangs

Hi, I'm running Zope 2.6.1 on Redhat 9, and am working through the online Zope Book. Roughly every hour or so, the Zope server hangs and I have to restart it. What would cause this? I'm considering Zope for a financial institution's internal processing ... is Zope really reliable and secure enough?
