Do you run periodic media scrubs on that raid array? And if it's not significant, then there's nothing that I can sugest that woul dhave caused the problem. For all we know about the state of the system at the time the problem occurred, it could have been caused by a cosmic ray flipping a bit somewhere in the IO path. i.e. trying to diagnose a failure like this without any other errors showing and no corrupt filesystem image we can examine is no better than trying to guess where the needle is in a haystack...
