Bug: Checking in a file geodatabase results in data loss when a split feature creates an overlapping OBJECTID that is deleted in the same edit session
This issue has been fixed at ArcSDE 9.3 Service Pack 1
Potential data loss occurs when checking in a file geodatabase after a disconnected editing session in which splitting a feature results in overlapping ObjectIDs that are then deleted in the same editing session.
The feature with the duplicate ObjectID on the parent SDE geodatabase is deleted after check-in synchronization.
The issue happens only when a file geodatabase is checked out, and when creation of overlapping ObjectIDs and the deletion of the same ObjectID happen during the same editing session.
This is a known issue.
Upgrade the installation with the latest service pack, if necessary.
