[Zope] zope database horror!

hi, i went through a nightmare just now. my previous zope database size was about 10M. that was last week. this morning, when look, it's 1.6G! how did it come to that? it really is scary. i tried packing the 1.6G data, but it stops responding after a while. restarted zope, and it takes about 10 minutes to load the 1.6G. i tried packing the data after stopping user access. the ppacked data ( takes about 20 minutes) is only 12M. so, any gurus out there can enlighten me? do i need to pack data nightly? biweekly? any advice appreciated. tq -- ------------------------------------------------------ http://www.kedai.com.my/kk Am I Evil?
