FlowPropertiesMaxUnackedMessages Property

This property may only be set when the Flow property AckMode is set to ClientAck. When set to a positive value, this property controls the maximum number of messages that may be unacknowledged on the Flow (Ack(Int64) is called to acknowledge messages and remove those messages from the message spool.) This property cannot be used to increase the appliance configured maximum number of acknowledged messages on the endpoint. When set to -1, the appliance configured maximum controls how many unacknowledged messages may be received by the application. Valid values are -1 and >0.
