This problem is caused when an item that is used for processing change events becomes corrupt in the database. After that, change events continue to be processed, but the item can no longer be updated. The failure to update causes the error message.

This problem is reported to occur when data is exported from a Jazz application while the server is running, after a server crash, and after migrations.
