      Description

      Code comment indicates this was due to occasional failures tracked in SERVER-16457, but this failure occurs every time with the attached db, and that ticket has been closed as fixed as of rc4. Corrupted db attached: 4 KB at offset 0x001ba000, which is a leaf node, have been overwritten with 0s.
