I can't figure it out whats going on here, do you have any clues ?
Any error like this is either the result of a bug in the skiplist
implementation (likely) or a bug in the write ordering of the
underlying OS (which assumes you've actually had a _crash_, not an
orderly reboot).
We've seen this once or twice on our seen state. I've reviewed the
skiplist code and haven't found any good reason for it. I haven't come
up with a nice way of gathering more information to debug.

It's trivial to make fun of Microsoft products, but it takes a real man to make them work, and a god to make them do anything useful.
