      moveChunk from shard0001 to shard0010 fail, warning log at shard0010:
      ----------------------------
      2015-06-05T10:02:27.999+0800 [migrateThread] warning: failed to create index before migrating data. idx: { v: 1, key:

      { _: -1 }

      , name: "__-1", ns: "xx.xx", expireAfterSeconds: 5227200 } error: IndexOptionsConflict Index with name: __-1 already exists with different options
      ----------------------------
      But I check these two shards's _ index they both have same “expireAfterSeconds”.

      After I restart all shards the moveChunk works fine, Is it a 'cached' bug?
