Ah.. then this behaviour is expected as these options(and corresponding
implementation) got removed with v4.0 due to its incomplete and/or incorrect
logic in various disconnect scenarios. It was decided to place lock-healing
logic in replication layer rather than on protocol-client. In case you are
interested refer the following doc for some notes around the internals of
lock-healing implementation and issues:
