[Zope-dev] mvcc related error?

(I tried to send this to zodb-dev@zope.org but got a relay error from ns2.zope.com :-S) Hi All, One of the users on one of my projects saw this error under high load: Module Products.QueueCatalog.QueueCatalog, line 458, in reindexObject Module Products.QueueCatalog.QueueCatalog, line 341, in catalog_object Module Products.QueueCatalog.QueueCatalog, line 284, in _update Module ZODB.Connection, line 732, in setstate Module ZODB.Connection, line 765, in _setstate Module ZODB.Connection, line 791, in _load_before_or_conflict Module ZODB.Connection, line 814, in _setstate_noncurrent AssertionError This is on Zope 2.9.4. Any ideas? cheers, Chris
