Hi Paul, It's certainly worth filing a bug over in launchpad about this.

[Zope] Frequent Zope crashes (Zope 2.9.8)
Hello, my Zope 2.9.8 instance crashes up to 6 times per hour. This is very unfortunate since the constant restarting brings performance to its knees. It runs under Linux in 64 bit mode on an AMD64 .
