My computer is saying that too much memory is being used and is shutting down randomly. The only few programs I run are League occasionally, Skype and Parallels Desktop. I have 8GB on RAM and here is a screenshot of my Activity Monitor.

In addition, my computer force restarted because of an error recently and some question marks have appeared in the taskbar. Is my computer memory becoming corrupted? It says 7.7GB of memory are being used... but not even that much memory is being used (you can add it up). Any ideas?

  • The ? icon is what the Dock shows when the application/file/whatever it pointed to no longer exists. If you deleted some application, but did not remove the Dock icon, it would show this the next time the Dock launches. – Alexander O'Mara Feb 7 '16 at 2:34
  • Thanks! Its possibly the reason (Maybe I was freeing up some disk space and forgot). Any idea on the memory usage? – k9b Feb 7 '16 at 2:36
  • This answer on Ask Different might help you understand total memory usage: apple.stackexchange.com/a/36068/70505 Info might be outdated though. – Alexander O'Mara Feb 7 '16 at 2:37
  • I would be suspect of the java process running as root. I'd run ps aux | grep 'java' in Terminal, and see what it is that's running. – Alexander O'Mara Feb 7 '16 at 2:40

If you're running a VM inside Parallels desktop it is possible, that this VM is allocating too much memory (8GB is not much, if you're running e.g. Windows 7 or 10 on a VM). To find out: Shut down your VM and go to the settings of the VM, where you can adjust the allocated memory partition for your VM.
