MBP Freezes Constantly (memorystatus_thread: idle exiting pid)

Question

My MBP freezes constantly and I get variations of the console entry shown above.  I get dozens per minute.  Here is just one minute's log:

This got so bad, that I reformatted my entire drive, reinstalled all of the Apple programs from scratch, and then only select third party ones that I always use (Microsoft Office, OmniFocus, Firefox, Evernote).  That's about it.  The main program that constantly stalls out, though, is Apple Mail. I have 80% of my hard drive free (240GB out of 300GB).  I cannot figure it out, and it's driving me nuts.  Any suggestions?

Dear Hampton, I have exactly the same problem with my MacBook Pro and it seems to be a RAM problem. I took it to the Genius Bar and sadly the truth, which the Genius bar guys were reluctant to admit, is that there are issues with the way the OS manages RAM, failing to clear Inactive memory and keep Free memory at a healthy level. If you go to the Activity Monitor and check the system memory I bet you will find that whenever you're seeing the "Exited: Killed: 9" lines one after the other as posted, you Free Memory would have been gobbled up by Inactive Memory. Extra memory would seem to be the permanent solution, sadly, and Apple charge an arm and a leg for it. Or you may have to live like I am at the moment, i.e. having the Activity Monitor permanently on the dock to keep an eye on Inactive Memory. When Inactive Memory gets too big I launch Terminal (Utilities) and type "purge." It frees up memory by clearig Inactive memory so that your machine's memory is as fresh as it is soon after you've started it. Good luck
