When I went into Activity Monitor, I noticed that a process called
storedownloadd was consuming 2.7GB of RAM and increasing RAM usage steadily (3.1GB during screenshot). However, it was not consuming any CPU cycles, and I am not downloading or updating anything. Why is it consuming so much RAM without using any or very little CPU cycles?
I also noticed that my compressed memory was 3GB. Is this linked to the process' RAM?
