Automatic failover - Mongoid 4.0.2 -

trying test automatic failover using mongoid 4.0.2 gem , using mongodb 2.4.3

to simulate i'm using test code:

require 'mongoid'  class testclass   include mongoid::document   store_in collection: "test", database: "test"    field :uuid, type: string end   mongoid.load!("config/mongoid.yml", :test)  batch = (1..100).map { |x| testclass.new({ uuid: x })  } batch.each_with_index { |x, i|   begin     x.save     sleep(5.seconds)     puts "saved #{i} records" if i%10 == 0   rescue exception => e     puts e.message   end } 

in between saves, jumped on mongodb , did rs.stepdown() on primary node of mongo cluster, unfortunately results in following errors in test app:

see https://github.com/mongodb/mongo/blob/master/docs/errors.md details error. moped::errors::operationfailure operation: #<moped::protocol::command   @length=68   @request_id=192   @response_to=0   @op_code=2004   @flags=[]   @full_collection_name="test.$cmd"   @skip=0   @limit=-1   @selector={:getlasterror=>1, :w=>1}   @fields=nil> failed error 10058: "not master" 

my mongoid configuration looks thus:

  test:   sessions:     default:       database: test_db       hosts:         - 192.168.1.10:27017         - 192.168.1.11:27017       options:         max_retries: 10         retry_interval: 1 

any idea i'm doing wrong here? thought mongoid driver automatically detect changes in cluster , automatically retry request after updates cluster state on client / ruby side?
