Choose the CC-Service component, the Memory Usage graph, and then check "all on same graph." This will result in a very busy graph, but if any service is showing a large spike in memory consumption, it should appear as a widening track on the graph.(Note: my image above only shows 15 minutes of gathered data as I didn't want to wait a full day to get you a "better" graph. For your investigation, you will likely need more data than I'm demonstrating here.)Since each service will list two data points ("Total RSS" and "Cache"), your graph may be difficult to read. For my lab system, 67 CC-Services * 2 data points = 174 graph points. If yours is similar, remember that you can hide data points by clicking on them in the graph legend.Once you have the memory consumption narrowed down to a service or two, let us know your findings?
