Massive Mountain Lion memory leak

So, here's my 2 cents (or 2 pence)

I have a 27" 2009 iMac with 16GB RAM. Free Memory is just 21MB. Inactive is well over 10.5GB. Running 10.8.2

I generally have multiple chrome tabs running, word and excel, thunderbird and skype. sometimes pixelmator, dreamweaver cs5 and ocassional parallels vm.

I could close apps to free memory but no matter what, free memory will just disappear and my hard disk starts thrashing again. Only way to solve is a reboot, but its temporary as the problem could be back a week later.

I ran the page outs command and see the following for the last 15 mins.

15:54:16 pgout/s

15:55:16 22.2

15:56:16 1.4

15:57:16 44.8

15:58:16 23.9

15:59:16 0.0

16:00:16 1.7

16:01:16 6.8

16:02:16 0.0

16:03:16 0.3

16:04:16 8.3

16:05:16 26.1

16:06:16 19.4

16:07:16 0.0

16:08:16 7.1

16:09:16 51.6

So theres definately a leak somewhere.

Here's hoping 10.8.3 fixes it.

In my Macbook Pro 4GB RAM recently note memory leak when I opened Safari even with 1 or two windows open without refresh the web content.

In Activity monitor could see consume Web Content the Safari Spend more the 2 GB RAM (Memory Real become Memory Inactive)

Solution: Disable All Extensions and probe one to one. Finding that Fastesttube Extension was responsible.

What are the units, bytes/sec, kilobytes? This is meaningless without units.

The terminal output isnt specific, but looking more at the sar command it seems the units are KB/s.

i've since rebooted so currently have normal system behaviour, but earlier today i had the problem. Essentially i have high inactive memory but hard disk constantly working throughout paging and/or swapping.

I understand that normally, inactive memory is or should act as a cache for recently used apps or data but in my case this doesnt appear to be working.

Open Activity Monitor, select the System Memory page and post a screenshot of the current page-out figures.

Turns out my friend's memory leak was related to a faulty hdd. He replaced that, then reinstalled all the software and everything seems to be running fine for him now.

Are you running Windows in a VM at all?

Yes, occasinally using parallels. i have two setup, one WinXP and one Win7. Both are run only when needed, maybe every few days, and never will both be running sequentially... but ive had these for some time back when running snow leopard and didnt notice this issue.

Your page outs are low to normal for a machine running a Windows VM, as is the large amount of inactive memory.

Reboot, use your Mac for a couple of hours without running either VM, then check the difference in Activity Monitor.

vm's aren't always a cause of.

Safari sometimes eat about ~10 GB of RAM. (from my 16).

Safari that's without addons. with 2 or 3 tabs. Opening one at 5, 10 hours.

Sometimes a couse of leaks is adium etc.

variously.

I haven't nothing oppose inactive memory, but that disk cache terminate active app to swap, if I in time don't change purge action.

alike situation is watched on ms windows (win7 as example), if you copy files under Total Commander etc. Use app that writes without a look at system specification of OS.

Google Chrome, Super Duper, carbon copy cloner etc.

For example, "Finder" doesn't create a such "problem" when you copy files under finder.

Sorry my English.

from Russia and don't know english enough. Just have simular problem.

My 2012 i7 Mac mini consistently uses about 2.5gb out of 16gb of total RAM to run just Mountain Lion with Plex Media Server in the background. My 2012 MacBook Air with 8gb RAM uses right around 1.5gb just to run the desktop. I feel like RAM usage was more efficient in Lion and definitely in Snow Leopard. I will probably be downgrading the Apple partition in my MacBook Air to 10.7 and hopefully regain some performance. The MacBook Air runs 64-bit Ubuntu EXTREMELY efficiently. Maybe the hardware isn't as restricted as it is in OS X.

VM's are ALWAYS a cause of extra page outs, you are incorrect.

Ubuntu is incredible on any platform.

I havealso looked at my activity monitor but i dont know what to do next. I have only 4gb and i cant run my Final Cut X effieciently. Pls give me steps to take to increase my system's efficiency.
