Memory (8GB) is just suddenly jumping to red, usually by some Safari tab (gmail etc) which suddenly jumps to 1GB. And that's it. No indexing or mds processes; just browser tabs which suddenly jump over a point and lock up everything because of memory use. It's like i'm back in the early '90s when I first touched a non Amiga and non SunOS system. And asked how people can work with that 'Windows/DOS stuff'. I am not sure why it misbehaves so much though...
