Failed attempt to read file?

I've noticed that I have several of these entries showing up in ADAudit, event ID is 4656.  Users associated with the event are not reporting a problem, and there doesn't seem to be an issue with the hard disks that the files are located on, but these entries are still popping up. Has anyone come across this before?
