*Created by: YoEight* This might be caused by a `protobuf` bug. Interestingly, this behavior doesn't happen with server version prior to 3.9. ``` Exception: ProtobufDecodingError "Failed reading: empty\nEmpty call stack\n" ``` When occurring that error might not be fatal for maintaining a connection with the server. However, in some situation (like initiating a connection for the first time), it could result to not being able to connect. Env: Linux and OSX GHC: 8.0.1 More investigation is needed. ps: Tried with a 3rd party Java 8 driver, didn't experience any issue.
