I forget if this was covered in the initial report, but did you try writing
to /proc/sys/vm/drop_caches (IIRC the usable values are a bitmask with
multiple possible bits to try)?

That would be expected to help if it is the OSes VFS cache that's getting
corrupted, as opposed to the AFS-specific cache.
