Hi again, After searching for recent posts related to Zope v.2.3.1, the Catalog, and BTree, I came across this one, from Chris M., which includes a small patch: http://lists.zope.org/pipermail/zope/2001-April/087015.html After applying the patch to: /lib/python/SearchIndex/GlobbingLexicon.py Xron has regained consciousness and started running jobs again, and has resumed writing coherent log entries. Thanks for Xron, and the tips! Jerry S.
