Yes, but I am not sure, or better I don't know who is causing these errors. I wrote up some stuff on finding the path of an object http://plone.org/documentation/how-to/debug-zodb-bloat/ and http://www.zopelabs.com/cookbook/1114086617 The scripts need to be updated for recent ZODBs (change one import I think).
