Claus, It looks like the problem with my json.
"ts": Timestamp(1415124334, 1), Once it is removed I had no problems. The json file is from Mongodb oplog. It is used to synchronize data between Mongodb and Redis. Do you have suggestions for dealing with that name: value pair? Maybe something along the line of message transformation? I really don't need the timestamp information.
