Re: [2.8.1]Received finish request for completed transaction (the message may be too late
You have set some value for the parameter TxTimeoutOnPartitionMapExchange. This means that you allow Ignite to rollback "long" transactions when Ignite wants to start a partition map exchange process. A "long" transaction (its duration) you define in this parameter.
Well, when you see the warning "Received finish request for completed transaction (the message may be too late)", this means that Ignite wants to rollback some transaction and have sent the appropriate command. But at the moment when this command should be executed, the transaction is already finished by itself.
