Hi! I have been using yosemite on my macbook pro retina 15" since the full release. Today I noticed something rather strange and annoying. I suddenly got popup from OS X that multiple programs has stopped responding and uses up a ton of memory, all of it in fact. See the attached pictures. The only tabs i had open was a 5 minute clip on youtube, and my webmail. And the memory went nuts and crashed, and it does it still as we speak. And I couldn't do anything or open anything else. I have tried using the PRAM reset without any results. I haven't tried SMC reset, but will begin it now and check back.
