[Zope] Zope database file grows when no one is modifying it

[Jamie O'Keefe]

Thank you Andreas and Martijn,

I checked the root undo log and that pointed me to to the problem.  It
proved to be spammers on one of our under used public boards.  Problem
solved for now.

Any suggestions as to how to thwart such attempts besides requiring
user accounts for even the most minor edit and then remaining vigilant
about who get accounts?

Thanks!

Jamie
