Not necessary. This is the linux top stats. In linux when the guest OS is under high memory usage, it will claim the demanded memory however, when the pressure is over, the memory won't be returned back and will be maintained as cache in case some of the data inside it is used later. At some point of time CUCM need 94% memory but that might be a spike and the server isn't under pressure now while it didn't return the borrowed memory.

Hope its clear. The actual memory usage can be seen from RTMT.
