> When group-transaction-events is set to true for a serial gateway sender, it is possible that events that were retrieved from the queue to be added to a batch in order to complete a transaction are later sent again in another batch due to a bug in the removal logic of events when the ack for a batch is received from the receiver.
> This situation has been seen when several clients are sending transactions to a Geode cluster when the events for the transactions sent by the clients are mixed in the gateway sender queue.
