What Is ‘kernel_task’ and Why Is It So RAM Hungry?
Every so often, I see MemoryStick reporting a lot of pageable RAM is being used. I checked out Activity Monitor and sorted by what was using the most memory. I found process 0 named kernel_task being run by root. It’s using little to no CPU at any given time, but has 36 threads and is using anywhere from 75 to 78 megabytes of real RAM and a little more than 745 megabytes of virtual RAM. The only thing I’ve been able to find by searching is old comments referencing certain HP drivers, USB ports, and OS X version 10.2.2. I don’t use any HP products, nothing is currently plugged into my USB ports, and I’m running OS X 10.3.2.
Please chime in if you know what’s going on here.
