Managing Conflict Errors in Zope
Sometimes, your Zope application may be unnecessarily writing too many times to the database. An easy way to track what objects are being written to is to use the analyze.py utility. Look at the Count and Pct, and make sure that relatively static objects do not get too many writes.
