Environment:Ubuntu 12.04 - 16.04 64bit, MongoDB 3.2.0 - 3.2.7, SSL enabled, plain authentication enabled
After upgrade to MongoDB from v3.0.7 to v3.2.6 started encountering Mongo::Error::SocketError: IOError. After some research found that happened each time when primary member in replicaset was restarted and elected as primary again.
Was reproduced with:
client = Mongo::Client.new(
[
"127.0.0.1:27017",
"127.0.0.1:27018",
"127.0.0.1:27019"
],
:ssl => true,
:ssl_verifyi => false,
:ssl_cert => "/tmp/mongodb/ssl/client.crt",
:ssl_key => "/tmp/mongodb/ssl/client.key",
:ssl_ca_cert => "/tmp/mongodb/ssl/mongodb.pem",
:read => { :mode => :primary },
:write => { :w => 2 },
:database => "test",
:auth_source => "admin",
:user => "user",
:password => "password"
)
client = client.use("test")
client[:users].insert_one(name: "John")
#stop primary member, wait for another member to be elected as primary
client[:users].insert_one(name: "Paul")
#start ex-primary and wait for this member to be elected as primary again
client[:users].find(name: "John").count
And we are getting this error each time:
Failure/Error: expect(@client[:users].find(name: "John").count).to eq 1 Mongo::Error::SocketError: IOError # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/socket.rb:195:in `rescue in handle_errors' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/socket.rb:190:in `handle_errors' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/socket.rb:122:in `read' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/protocol/message.rb:113:in `deserialize' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/server/connectable.rb:107:in `block in read' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/server/connectable.rb:91:in `ensure_connected' # /home/deply/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/server/connectable.rb:106:in `read' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/server/connection.rb:158:in `deliver' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/server/connection.rb:104:in `block in dispatch' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/monitoring/publishable.rb:47:in `publish_command' # /home/deploy/.rvm/gems/ruby-2.3.0/gems/mongo-2.2.5/lib/mongo/server/connection.rb:103:in `dispatch' ...
