Hi all. I know ReadConflictError should be normal inside Zope Transactions. However, I've 4 or 5 of this errors each day: 2005-03-08T10:01:51 ERROR(200) KeywordIndex unindex_object could not remove documentId -895169661 from index workitems_from. This should not happen. Traceback (most recent call last): File "/home/zope/zope-2.7.4/lib/python/Products/PluginIndexes/common/UnIndex.py", line 185, in removeForwardIndexEntry indexRow.remove(documentId) File "/home/zope/zope-2.7.4/lib/python/ZODB/Connection.py", line 599, in setstate invalid = self._is_invalidated(obj) File "/home/zope/zope-2.7.4/lib/python/ZODB/Connection.py", line 628, in _is_invalidated raise ReadConflictError(object=obj) ReadConflictError: database read conflict error (oid 0x317235, class BTrees.IIBTree.IISet) Is there something I should worry?
