    • Type: Icon: Bug Bug

    • Affects Version/s: 2.1.0
    • Component/s: Public API
    • Labels:
      None
    • Environment:
      Linux
      Mongo 3, wiredTiger

      Run long operation and interrupt 

      client = Mongo::Client.new(ENV["MONGODB_URI"])
client[:locations].find.distinct :zip 
^C
client[:locations].find.count

      Depending when interruption was occured I occur 2 kind of errros.
      1. Mixed response
      first time: 

      client[:locations].find.count => 0

      second time: 

      client[:locations].find.count => 758299

      next: 

      client[:locations].find.count => 758299

      But after I run different operation
      first time: 

      client[:locations].find.first => {"n"=>758299, "ok"=>1.0}

      second time: 

      client[:locations].find.first =>{"_id"=>BSON::ObjectId('554b4ede69702d60b3000000'), ...}

      Then running count again gives 0 and then good count.

      2. KeyError: key not found: "7", KeyError: key not found: "9", ...., KeyError: key not found: "a", KeyError: key not found: "o" and so on after each call.
