What is a system memory "page out"?

I heard that looking at "page outs" in activity montor (under system memory) is a good way to know if you need more ram. Can someone explain what a page out is? What % of page outs represent a problem?

You can find a good summary of memory management in Mac OS X here. That should give you a good backgrounding.

OS 10.8.5 on iMac grinding to a halt - fairly usual CPU but up to 7GB Page outs after starting Safari (I think)

Hi
I'm running OS 10.8.5 on an iMac (early 2009, 4GB memory), which has been running fine up until today:
Applications started becoming very unresponsive, and eventually beach balled until it became unusable. Restarts didnt cure it.
Having looked in the Activity Monitor from suggestions in discussions here, the System Memory 'Page Outs' seemed high, at 7GB
For a while, if I didnt run Safari, it seemed to stay at 0
Once I've run Safari, the Page Outs keep climbing, even when Safari is closed
The Page Outs are raising at between 1MB/sec and 7MB/sec, which i think seems high based on reading people's comments
(CPU usage seemed fairly normal, except for an occaisional 'Safari Web Content' jump to 20% once in a while)
Im using Safari 6.0.5, and aside from Java being enabled (I've tried turning it off, same effect), theres nothing unusual about what I'm doing in Safari
Any ideas about what could be causing this / what to do?
Many thanks in advance

There is excessive swapping of data between physical memory and virtual memory. That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
Another process often implicated in memory leaks is "inkjet8," which is a component of the HP printing softwre. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. If you don't use an HP printer, remove the software. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

PLUG-INS AND SYSTEM MEMORY

i am using only 2 plug-ins for now,called BFD acoustic drum module by fxpansion and ivory by synthogy. using the activity monitor i have been trying to find out what is causing logic to freeze.it shows the dock shooting as high as 15% CPU for short bursts,window server as high as 8% CPUand something called pm tool as high as 8%.this is before i turn on logic and the motu interface. according to this activity monitor i have 3.46G system memory left out of 4G.when i turn on logic pro 7.1 there is 3.29G left in sys. memory.this aint bad considering i have 5 of logics virtual instrument presets on.when i load the BFD drums it drops to 2.61 sys. memory.when i hit the play in the transport and the presets play in BFD,sys. mem stays the same and logics shows 80 to 120% CPU.when i turn it off it drops back to from 5 to 30% CPU, but the system memory stays the same at 2.41G. Only if i remove BFD completely from logic does tyhe system memory go back to 3.27G left. ivory does the same thing.
Is there any setting to make these 2 plug-ins not suck all of that ram memory up when i am not using them? ivory can draw over 1G of system memory when i use certain settings and the only way to get around sucking up the ram when i am not using it is to remove it asa plug-in and reboot logic,it will not give up the ram even when i remove it.i actually have to reboot logic for ivory to give up its ram. this can't be possible,what am i missin here?
Also this dock thing at times hangs up (turns red and actually says "hung", lol. in fact it just hung right this momeny and it is using from 70-95% CPU.How can i optimize this comp. so these things don't happen. i want to learn how to turn off EVERYTHING AND ANYTHING i don 't need to have on to run logic.
thanks in advance for any help

That's not the way memory works. When a program requests memory from the operating system, it's not fully returned to the OS until the program exits. So, even if you unload Ivory, that memory is still allocated to Logic. If Ivory supports streaming from disk, turn that on.
Your dock issue is probably something unrelated to memory. I'd create a new user account, don't load any 'startup at login' items, no neat gadgets from the 'net running in the menubar. Add minimal programs (Logic, Audio Midi Setup) to the dock. It shouldn't misbehave. You can't get rid of the dock, and shouldn't need to.
From what you've written, there's no indication that you don't have enough RAM, or that faster drives would help. The thing to watch for (as far as RAM is concerned) is the 'page outs' number in Activity Monitor. If you have enough RAM, it won't steadily increase (though it may not stay at 0). If it's steadily increasing while you run Logic, performance will suffer.
I've only run Logic (7.1.1 and 7.2) on Tiger, and haven't had problems like that on my PowerBook with 1.5G RAM, or the Quad with 4.5G. I don't have Ivory or BFD - they're notoriously RAM and CPU hungry plugins.

Shared memory (System V-style) - High usage of phys memory and page outs

Hi!
I get a much higher usage of physical memory when I use shared memory than I would expect. Please, I would really need someone to confirm my conclusions, so that I can revise my ignorance in this subject.
In my experiments I create a shared memory segment of 200 MB and I have 7 processes attaching to it. I have a ws of 1 GB.
I expect to see what I see when I attach to the shared memory segment in terms of virtual size, i.e. SIZE in prstat. After attaching (mapping it) to the process all 7 processes are about ~203 MB each and this makes sense. RSS, in prstat, is about 3 MB for each process and this is ok to me too.
It is what I see when each of the 7 processes start to write a simple string like 'Hello!' in parallel to each page in their shared memory segment that I get surprised. I run out of memory on my ws after a while and the system starts to wildly page out physical memory to disk so that the next 'Hello!' can be written to the next page in the shared memory segment. It seems that each page written to in the shared memory chunk is mapped into each process private address space. This means that the shared memory is not physically shared, just virtually shared. Is this correct?
Can memory be physically shared, so that my 7 processes only use 200 MB? ISM? DISM?
I create a shared memory segment in a C-program with the following calls:
shmid = shmget(key, SHM_SIZE, 0644 | IPC_CREAT)
data = shmat(shmid, (void *)0, 0);Thanks in advance

Your problem seemed reasonable. What were you doing wrong?

Keep getting the 'system has run out of application memory' window, what to do?

I'm running a mid 2010 MacBook with 2.4 Ghz Intel Core 2 Duo processor and OS X 10.9.5. Every time I'm on Safari I get the 'System has run out of application memory' window and it asks you to quit out of programs you're not using. The problem is sometimes the only things running are Safari and Finder. It'll then freeze up programs and prevent web pages from loading or showing up. I'm not quite sure what this means or how to go about fixing it. Any help would be much appreciated.

Hi Meghan,
If you are seeing that alert that you are running out of application memory then I would take a look at using Activity Monitor to see how the memory is being used. If it looks normal usage to you, then you may want to upgrade the memory on your Mac. Take a look at the article below for more information.
OS X Mavericks: If your Mac runs slowly
https://support.apple.com/kb/PH13895
How to use Activity Monitor

What can I do when it says "your system has run out of application memory?

What can I do when it says "your system has run out of application memory?"

The message has nothing to do with low disk space.
There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
          A long-running process with a memory leak (a kind of bug)
          Not enough memory for your usage pattern
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 ("Mavericks.") The procedure may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
          View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, remove the software. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total

Mavericks Mail Kernel System Has Run Out of Application Memory

I have a new Mavericks late 2013 MBP. When I got the computer, I used Migration Assistant to transfer everything from my late 2008 MacBook to the new MBP. Now when I launch Mail, my memory use skyrockets and within a minute or so, I get a "run out of application memory" error message. Soon after the computer stops working until I reboot. Activity Monitor shows Memory Pressure at its redline max, Virtual Memory at about 70 GB, Swap Used 20 GB, Compressed 10 MB. The processes using all the memory are kernel-task 10 GB and mds_stores 5 GB. However, Spotlight is fully indexed and mds is inactive until I launch Mail.
Interestingly, it happens even if I quit Mail immediately after launching it - the Mail window doesn't even need to open; the memory ust still climbs. But it only happens with Mail; all other applications work fine. Also, it does not happen if I boot in Safe Mode or if I log in using a different user account.
I have spend many hours on the phone with the Apple tech guys, they sent log files to Apple engineering, and none can figure this out. Their solution is to work around by creating a new user and transfer files over - not an elegant solution...
I ran the diagnostic suggested by Link Davis; results copied below. I also ran the Etresoft diagnostic both before and after launching Mail. Results also copied below.
I am guessing that a 3rd party application in my user area causes Spotlight to loose control, when Mail is launched, perhaps trying to index 10,000 emails, but I really have no idea!
Any help would be GREATLY appreciated!

Have you looked into Activity Monitor utility to see what system resources exist and how they are being allocated to applications, the OS X, and other background functions?
You could boot in SafeBoot (shift key held through startup) and run Disk Utility> repair disk permissions. That can tell you a few things about your hard disk drive, capacities, and it may not hurt to repair disk permissions. Restart normally when done.
Or try & boot from the Install DVD and use the version of Disk Utility in there to attempt to 'repair disk' while the HDD is unmounted. Then choose Startup manager to boot from the HDD and ignore the DVD on a restart.
Is your computer as listed, a PowerPC (pre-intel architecture)
Apple product, with a G4/G5 CPU from before 2006? If so,
a host could move the discussion from this Intel area.
Without more information, a failure of traction results from speculation.
Is your computer still running OS X 10.5.3, or is that 10.5.8+ now?
Good luck & happy computing!

'Your system has run out of application memory'?!

I've seen many users experiencing this same problem throughout the community, but none of the fixes have given me a permanent solution. Details of the machine are below, as well as what happens when the problem hits/triggers.
MBP Retina running OS X Yosemite 10.10.2 (occurred in previous versions as well, thought the latest update would help but it didn't)
15-Inches Mid 2014 with 16 GB of Ram
Been using this Mac for good 6 months now, and one fine day of normal usage the whole system seems really laggy and slow and all of a sudden i'm unable to access anything and barely move my mouse. Then, a window pops out, telling me "Your system has run out of application memory", gracefully showing me that I have to force quit all my programmes for me to just stare at my desktop in utter disappointment.
I've been using Yosemite for awhile now (updated few days since the release) and haven't encountered any major issues, this being the first. Reading through many threads many have said that the problem lies with opening the Mail app, yet I haven't touched that app in months. I've also tried resetting the PRAM on my machine when it happens and the problem comes back again after several minutes of normal usage (iTunes, App Store). Checking the memory usage with the Memory Clean app, it tells me I'm down to a measly '15.58 MB' of memory, and it justfluctuates at that until I give it a restart again. This can't keep happening - I can barely use the Mac for 10 minutes without having to restart it, only to be able to use it only again for another 10 minutes.
Opening Activity Monitor tells me that mds_stores is the main root of the problem, yet I can't seem to shut the process down. I've googled and many say that mds_stores is spotlight indexing, but taking up all 16 GB of ram? That shouldn't be the case. Is there a fix to this? Does Apple know of its existence?

☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign ($) to appear.
The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.
The Terminal window doesn't show the output. Please don't copy anything from there.
If any personal information appears in the output, anonymize before posting, but don’t remove the context.
Step 2
Enter the following command as in Step 1 and post the output:
mdutil -as 2>&- | pbcopy
You can then quit Terminal.
Step 3
Launch the Console application in the same way you launched Terminal. In the Console window, look under the heading DIAGNOSTIC AND USAGE INFORMATION on the left for crash reports related to Spotlight. If you don't see that heading, select
View ▹ Show Log List
from the menu bar. A Spotlight crash report has a name beginning in "mds" or "mdworker" and ending in ".crash". Select the most recent such report, if any, from the System and User subcategories and post the entire contents—the text, please, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post any other kind of diagnostic report, such as hang logs—they're very long and not helpful.

"Your system has run out of application memory"! Help, please! Thanks!

Hi,
Just got the unsettling message saying "Your system has run out of application memory" and I was instructed to close down applications I wasn't using, including browsers, or I might have problems with my computer. Yeesh. This is scary. Is the solution to buy more RAM? Bear with me, I really don't know what to do, and I'd appreciate your help.
Thanks,

Tried to update my product listings, but it wouldn't work. I have OS X Mavericks, 10.9.2 on my iMac desktop.

There is excessive swapping of data between physical memory (that is, the memory chips on the logic board) and virtual memory (one or more files on the startup volume.) That activity is relatively slow and causes the whole system to be less responsive. It can happen for two reasons:
A long-running process with a memory leak (a kind of bug)
Not enough memory for your usage pattern
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
These instructions are for OS X 10.9 ("Mavericks.") The procedure may be slightly different for earlier versions of OS X.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the View menu, if it's not already selected. Select the Memory tab. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The processes named "Safari Web Content" render web pages for Safari. They use a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider them prime suspects.
Another process often implicated in memory leaks is "inkjet4" or "inkjet8," which is a component of the HP printing software. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. Empty the print queues in the Printers & Scanners preference pane (which has a slightly different name in each recent version of OS X.) If you don't use an HP printer, remove the software. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
"Wired" memory should be a small part of the total. That memory is not swapped, but it makes less physical memory available which may then result in swapping. If you have a lot of wired memory, that's usually an indication of a memory leak in a third-party program that modifies the operating system at a low level. Ask for guidance in that case.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

My MacBook pro 2012 Mountain Loin 8.2 don't clear the inactive memory automatically when memory needed for other program so I get page outs.

My MacBook Pro 2012 Mountain Loin 8.2 doesn't clear the inactive memory automatically when memory needed for other program so I get page outs. There are much inactive memory when page outs. Why my mac does this?

That's completely normal. If other programs require memory then the system will reallocate Inactive RAM as needed. Page Outs don't mean anything.
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

I've updated my Macbook Pro and my iMac with Maverick, updating the various apps. On my Macbook, everything functions perfectly. On my iMac, I get the Your System has Run out of Application Memory, and it's based our Mail, the only app not updated. Ideas?

Maverick and Your System message
I've updated my Macbook Pro and my iMac with Maverick, updating the various apps (Pages, Aperture, iPhoto, Numbers & iMovie, too) in the process.
On my Macbook, everything functions perfectly. On my iMac, I get the Your System has Run out of Application Memory message. But it's not Calendar, it's Mail that not only won't open, but when it does now, it takes the entire system out with it.
I open Safari, and it works. I open Firefox, and it works and Safari still works. I open Calendar and it works, Safari and Firefox continue to work. I open Reminders, and everything still works.
I open Aperture, and it opens Finder instead, showing the 3.5 update that was installed two days ago (and Aperture has functioned), but doesn't seem to update the app; after about 20 seconds the update disappears and I can now open Aperture and it shows I'm now opening the updated Aperture, which it didn't show before.
I click on Mail, and the cursor spins for ten minutes. The mail window finally opens, but the cursor spins and does not connect to upload new mail, and I finally Force Quit Mail. Since the Maverick update, even though Mail was not updated (and maybe because Mail was not updated), I have been able to receive emails twice, and then the program crashed.
Besides the Aperture app, Pages didn't fully update on the iMac, and I had to remove the old Pages icon from the dock after the new program loaded up from Applications.
Any ideas?

Your system has run out of application memory Premiere pro cc 2014

Hi,
I've been getting the "your system has run out of application memory" message while working on a new project in pr pro cc.
Here's what i've done so far:
Updated to OS X 10.9.5 and restarted computer
went into my activity monitor and stopped programs that were taking up memory, but that didn't solve the problem the message would pop up over and over again.
this is the first time i've seen this message. I installed the universal free trial red giant plug ins for PR Pro . I'm starting to think that the plug ins are the problem.
I used several of the universal plugins from red giant on my entire project. I was able to export the project twice w no problems but then when i went back into the project and the notification kept popping up!
I'm using
PLS HELP!!!
thanks!

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, look under the heading DIAGNOSTIC AND USAGE INFORMATION on the left for crash or panic reports. If you don't see that heading, select
View ▹ Show Log List
from the menu bar.
A crash report has a name that begins with the name of the crashed process and ends in ".crash". It may be under either of the two subcategories, "System" and "User." A panic report has a name that begins with "Kernel" and ends in ".panic".
Select the most recent of each and post the entire contents — the text, please, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)

Hi i upgrade from lion to mountain lion to day on my mini mac,Since the upgrade i am getting no sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever

Hi i upgraded from lion to mountain lion to day on my mini mac,Since the upgrade i am no longer getting sound through my HDMI cable which was working fine on lion Checked the midi audio settings and system preferences to out on HDMi nothing no sound whats so ever.Any one any ideas?
I use a samsung TV for my monitor via HDMI.Tried all the system Audi setting nothing .Head phone and internal speakers are fine.

Similar issue; Audio was working fine on Lion, now not on Mountain Lion. Have a Macbook Pro early 2011 with AMD Radeon HD 6750M, connected by thunderbolt through a Lacie LBD to a mini-displayport to HDMI adapter (n.b. same problem when not going through the LBD) to a Pioneer VSX 521 AV receiver. For me when I go into audio Midi settings all the volume sliders for the displayport device are greyed out and at zero. But when I click 'configure speakers', it's able to send out the test signals to each speaker. Part of the problem could be that I'm not getting the option to put out 6channel sound, only 2 or 8 channel. Since my system is Dolby 5.1, and I only have 6 speakers, I would have expected the 6ch option to be available. But I imagine there's more to it than that. Elsewhere someone has suggested playing with Remote Interactive over HD on an Onkyo device; I'll see if there's something similar on the Pioneer that can be changed. Any other suggestions welcome.

How to know the amount of ora 11g page-out memory (sga and pga)?

How to know the amount of oracle 11g page-out memory ( sga and pga) in the SunSolaris 10 Unix and Linux.
I need to know how many oracle memory are being page-out ( all and for a one oracle server process).
thanks

You can monitor the paging with vmstat or sar commands.
http://download.oracle.com/docs/cd/B28359_01/server.111/b32009/tuning.htm#sthref500
You can also get the paging information on OEM home page if configured for your database.
But I don't know if there exists a method with which one can find out how much memory per session/server process is getting paged out.

What is a system memory "page out"?
