Justin, by the way, what's the underlying filesystem on the server?
I've seen this error on 2 machines already (both running 2.6.29.x x86-64), and in both cases the filesystem on the server was xfs. May this be related somehow to http://bugzilla.kernel.org/show_bug.cgi?id=13375 ? That one is different, but also about xfs and nfs. I'm trying to reproduce the problem on different filesystem...
