I're recently checked the memory usage of my vcsa an noticed, that in some cases the MaxMB value surpasses AllocatedMB by a large extent:

What would be the best course of action? Overall, the memory usage is not reaching the limit (~21GB CurrentMB vs ~24GB allocated), but I think some of the services (invsvc, vsphere-client) do not get enough memory. Should I increase the total amount fo RAM and increase the allocations by hand? What is the reason behind MaxMB > AllocatedMB, is AllocatedMB just a reservation? How is MaxMB calculated?
