Hi Lahiru, I saw the following code when calculating required instances. Since it is checking the instanceRange > 0, whenever the cluster instance reaches it maximum, this instanceRange is 0. At that point even though the load is high no decision is taken as the required instances is not getting calculated. Also, it is not notifying the parent as well even though it is max out.
Shall we remove this check which will help to predict the required instances even when the max is reached. So that we can notify the parent about the max out. Thanks, Reka -- Reka Thirunavukkarasu Senior Software Engineer, WSO2, Inc.:http://wso2.com, Mobile: +94776442007
