8GB of RAM, still not enough!

Hello,

Now, I've read all of the stories about the "intuitive way" Mac OS handles RAM, and how the memory displayed as "Inactive" is perfectly normal, and will be adressed to other applications when needed.

Well, I'm kind of concerned about that now. When using heavy applications like Logic Pro and Safari alongside eachtother, My 8 glorious gigs get depleted almost immediately and I'm stuck with about 60mb of free ram and about 4 gigs of inactive ram. Well, this is where this "memory addressing" should kick in right? Well, not a second later Logic Pro gives me his death note about not enough memory available, and there goes Logic Pro, closed.

Same goes for other applications, if they don't force-quit, the spinning ball of doom shows up.

So, I'm kind of curious, is Mac OS one big gaping memory-leak, or could there be something else going on?

(for additional info: I've had this issue ever since Snow Leopard)

Thanks in advance!

My personal opinion is that Lion and more so Mountain Lion have memory management issues that cause problems.

These include: Reboots, apps that fail, slow downs.

Welcome to the "new' iOS X. Since "Lion", Apple engineers seem more interested in making OS X feel similar to iOS for new adopters and all the iDevice users while focusing less on what made OS X such a great platform, the OS ;)

As an ADC member since 10.1, developers have witnessed this since "Snow Leopard", and much to our surprise many bugs are still open and unaddressed since "Lion". Memory management being one of many.

"Mountain Lion" may have improved, but it still is a long way from what "Snow Leopard" offered. Also, don't believe those that claim inactive RAM is a waste and the OS uses all the RAM and handles it, blah blah blah. It's blatant rhetoric, and as your situation clearly demonstrates, is false. I have 16GBs RAM on my 12-Core Mac Pro, and running Final Cut Pro X with other apps, it's been a far cry from "Snow Leopard".

It seems like ML doesn't release RAM if the application is still open. I use iFreeMem (which probably just uses a terminal command) to clear my RAM from time to time when using applications that eat RAM...

Snow Leopard has been the last great OS X version Apple has released. Agree completely.

Seems like they got issues and don't fix them because they think people usually have way more RAM than they need anyway.

I posted in another thread about my inactive memory problems but received no response.

I have a 2011 2.2GHz i7 with 8GB of RAM and if I open up chrome, inactive memory jumps above 3GB and free falls below 100MB (ususally below 50mb lately).

Running 'purge' doesn't clear the 3GB of inactive - it just clears a couple 100MBs that soon leak back out.

What the heck is Chrome storing that keeps creating 3GB of inactive memory?? If I quite chrome > restart > re-open chrome (40+ tabs), it doesn't jump to 3GB+ inactive until the last few tabs load...

Is there a way to just clear this excess 3GB that chrome keeps holding onto?? No matter what I do to clear up chrome (delete local storage, shockwave cache, flash cache, extensions, etc.), it always returns when I start the app up.

I'm so tired of the color wheel and bi-hourly restarts...

Any suggestions? I've google the heck out of this issue and there's a lot of discussion on it. But no one seems to have an answer that addresses the cause. Apps like "Free Memory" don't speed things up for me at all. If anything, they make things worse (if that's even possible)

Thanks.

40 tabs? How can one person "read" 40 tabs simultaneously?

Do you have adblock for Chrome installed? It increases memory usage dramatically.

I currently have 128mb "inactive" even after days of use and no reboot.

I don't think the problem is caused by a single application. There's something going on at a system level that causes the available memory to fall to almost zero for no apparent reason. At first, I blamed Safari and switched to Chrome but the problem persisted. Then I restarted with no applications running, purposely avoided firing up ANY browsers and just opened up Mail and another non-memory intensive application but to no avail. I was hoping that the 10.8.1 update would fix it but the problem reoccurred immediately after updating. The only thing that works for me is to use an app like "Free Memory" (free in the App Store). The fix doesn't usually "stick" the first time around. In fact, I typically need to free the memory five times or more before my system settles down. Even after that, the issue can randomly reappear after a few hours.

It would be easier for everyone to help if you would post up a screenshot of your activity monitor window, with processes arranged by real memory usage.

Try Firefox on the same configuration.

I don't think the problem is caused by a single application.
The problem is the WebKit/WebKit2 framework. Safari uses this framework and had memory management problems in Mac OS X 10.2.x, 10.3.x, 10.4.x, 10.5.x, 10.6.x and 10.7.x. It is a well known WebKit/WebKit2/Safari problem. The problem disappears if you reboot your machine, and if you use a non-WebKit browser, such as Firefox.

Right, except that: (1) I've never experienced this issue before despite having used all previous versions of OS X and Safari; and (2) as I wrote above, I reproduced the problem after a restart and without starting up ANY web browsers.

I have 8GB of RAM and even though I don't love Firefox by any means, it's my primary browser. Using FF and some other applications, I'm still getting about 1.88GB of free RAM.

If all else fails, it's worth giving FF a try.

Is Logic Pro the only app that complains about free memory? I'm on 4GB with a MBA and running multiple VMs, Xcode, and more I never have any crashes - not even due to lack of RAM. Sounds more like an issue with Logic Pro and not with the OS unless there are other apps displaying the error and closing.

Logic Pro is the cause of your woes Im afraid. There are numerous threads on Logic Pros issues with memory and they all exist regardless of the OS you are running on. You should take a trip to: http://www.logicprohelp.com/forum/viewforum.php?f=1
Chances are someone on the Logic forums will be able to assist you.

I was the one who was plagued with memory woes under SL and Lion. ML improved on these things amazingly well - it's for me the best OS X release yet (of course I would have loved Rosetta to be still supported).

i dunno...i run logic all the time, often with safari open (10-12 tabs open).
mail is running (and the usual iapps: calendar, notes, reminders).

altho it's rare, i sometimes get a memory error in logic (8gigs ram, 10.8.1).

am you using airport? try turning it off, rebooting. sometimes, after working on several large logic projects, i will get an error. i reboot, and open ONLY logic...
and work. and eventually, open safari, etc etc.

pretty rare tho.

Do not use WebKit or WebKit2 based browsers (Chrome, Safari, ...), if you need more than 20 open tabs.
I just opened 42 tabs with different webpages in Safari. Activity Monitor reports 906MB free memory on a 4GB system. My system doesn't feel slow at all.

*edit* Now I opened, and have running, every major application on my system, including all of iWork and iLife, along with Safari's 42 tabs. 429MB free and still running smoothly.

I think, since Lion (possibly SL), the inactive memory is freed after a longer duration and after making sure the process that allocated that space is fully terminated and chances of re-spawning it are low. Can't say who is the culprit here: Apple or BSD?

Also note that a decent part of the inactive memory is disk cache and can be freed using the purge command.
