Is this error really as straight forward as it looks? It’s happening on a user’s machine, so I don’t have direct access to check what is causing this. Could it be a simple case of file locking at the app or OS level?

Bizarre - it’s a new one for me.

A new one to me as well. Could be a locked file or an issue with their hard drive. I would suggest that you have the user run disk utility to eliminate that possibility.

Thanks Marcus, will do. The only other thing I can think of is that I’m overloading with saves somehow - I call save: on my managed object context on a 3 second delay each time NSManagedObjectContextObjectsDidChangeNotification fires (although in theory that’s not happening a lot).

Just ran the Instruments Core Data tools over my app - nothing of note. It’s actually wonderfully efficient (thanks to your book!).

I’ll ask the users to run disk utility and see if there’s anything unusual going on.
