I can't help but wonder how much these are affecting your performance. That's a lot of extra messages, and even more effort to log the failures. When I run your tests myself, I don't see any of these and I don't see a performance drop-off either. Maybe something ACL- or SELinux-related? It would be extra-helpful to get a stack trace for just one of these, to see where they're coming from.
