Here's another idea...
The copy engine also takes a "reservation" on objects while copying so
that an item being written to by one instance of the copy engine
cannot be copied by another instance while it is incomplete. Could a
Finder copy or Time Machine backup be in progress on the user's system
when your code gets this error?
That's my suspicion too, but a culprit isn't obvious. I had the
user do an lsof immediately after the failure and the only open
files were the usual spotlight and fsevent files. None of the
files in my archive package were open by any process.
Spotlight shouldn't be a problem. My product includes a
spotlight importer that reads specific index files in the
package (not the ones I'm having problems with). This is a
backup utility, so I doubt they have Time Machine taking backups
of their backups, but I'll ask. Ditto for a Finder copy.
