Any suggestion for a temporary fix would be very welcome, since we get about 6000 conflict errors per day now about 15 % unresolved, and they are really killing our portal. A workaround might be to replace the DateIndexes for 'created' and 'modified' with FieldIndexes: you will see a big jump in the number of keys in the index, but (perhaps) a reduction in conflicts (altheough there will be more bucket splits, which can also cause conflicts).
Unfortunately that does not work the FieldIndex also gives an conflict-error <FieldIndex at Date> <Products.ZCatalog.Catalog.Catalog object at 0xb250a6ec> <CatalogTool at portal_catalog> <CPSDefaultSite at uniben> <Application at > {'Application': <Application at >, 'ZGlobals': <BTrees._OOBTree.OOBTree object at 0xb242989c>} 2007-06-01 20:23:41 INFO ZPublisher.Conflict ConflictError at /uniben/campus/students/A923157/study_course/create_level: database conflict error (oid 0x36c429, class BTrees._OOBTree.OOBTree, serial this txn started with 0x036e0590d58661ee 2007-06-01 17:52:50.044906, serial currently committed 0x036e059346ef95dd 2007-06-01 17:55:16.625597) (1 conflicts (0 unresolved) since startup at Fri Jun 1 19:54:43 2007)
A longer term solution might be to come up with a derived index type which used non-persistent objects (rather than the IITreeSet used by UnIndex) for the set of RIDs stored under each 'minute': you could then inspect the state and do more aggressive conflict resolution than the stock implementation allows (see my other post).
any other shortterm suggestions.
