When resource consumption gets to a level considered to be high, a resource warning indicator appears at the bottom-right of Altium Designer. Hover the cursor over the indicator for information about which resource(s) are exceeding associated levels of consumption. Note that the color of the indicator changes to highlight the level of resource consumption.
