      This happens very rarely on a tiny fraction of similar queries. The query that produced it was of the form:

      db.mycollection.find({ $and: [ { base_map_loc: [ 182, 156 ] }, { _id: { $ne: "s1588142_270" } } ] })

      where there is a geo2D index on base_map_loc with parameters {min:0, max:1024, bits:1}
