Wired Memory

I was working on a 1.25 GHz G4 iMac with 1 GB of RAM. It seemed to be sluggish, so I launched Activity Monitor and checked for an explanation of the problem. The "Memory" view showed that over 800 MB of RAM was "wired". When I rebooted that value went down to under 200 MB. Can anyone offer an explanation of why that "wired" RAM value was so high? I can't give an accurate explanation of what might have been running before on that computer since the last reboot, but at the time I looked at it there wasn't much running at all.

Here's one explanation.

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.

  • Wired memory does not clear after safe boot

    My iMac started freezing up about a month ago when I was watching a video and would only boot up in safe mode. I noticed in Activity Monitor that 5.30 GB of memory was "wired" (out of 8 GB total). I was able to boot normally after cleaning the caches.
    The problem has gotten worse and the iMac now freezes after a short while of playing video.  As of now I can ONLY boot up in safe mode and Activity Monitor always shows 5.30 GB of wired memory, however no processes are using more than 1% of CPU (other than Activity Monitor itself). 
    Today I downloaded and tried a couple of memory cleaner apps just so I could reboot normally, but the wired memory (5.30 GB) won't budge.  After doing some research I learned about the kextstat command to see what memory is being wired.  This is the process using the most memory (assuming that longer numbers are the largest):
    71    0 0xffffff7f80e98000 0x1aa000   0x1aa000   com.apple.kext.AMD4800Controller (8.1.2) <70 69 10 9 5 4 3 1>
    Also, here are the last 2 lines from the SYSTEM LOG just before the freeze (each line was repeated 7 times):
    7/2/13 12:44:23.325 PM coreaudiod[272]: Enabled automatic stack shots because audio IO is inactive
    7/2/13 12:45:21.280 PM coreaudiod[272]: Disabled automatic stack shots because audio IO is active
    Any suggested next steps in troubleshooting are appreciated.

    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.  
    These steps are to be taken while booted in safe mode.
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal 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 Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    for k in {,/S*}/L*/E*/{,.?}*.kext; do test -f "$k/Contents/Info.plist" && /usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$_" | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo $k; done | open -f -a TextEdit
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    sudo defaults read com.apple.loginwindow LoginHook 2> /dev/null | open -f -a TextEdit
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3 
    Repeat with this line:
    ls -1A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 4
    osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null | open -f -a TextEdit 
    Remember, Steps 1-4 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • Additional ram = more wired memory?

    Quick question. I have upgraded to 4gb of ram today, and noticed that my wired memory has jumped from 140mb or so, to 422mb now... Is this normal? I add up some of the processes, and it doesn't add up to 422mb.... Does my wired memory allocation increase as my total memory does?
    Can someone tell me what their numbers are?
    Listing some of my info...
    Free 2.85gb
    Wired 424mb
    active 580mb
    inactive 170mb
    Firefox using 148.9mb
    kernel_task using 71.98
    Mail 55mmb
    windowserver 44mb
    The remainder under 20...

    Rod thank you for that second link, i hadn't read that one before. I did do my google searches though!
    The reason i was concerned is that from a fresh reboot i'm straight away at 460mb in the wired memory pretty much leaving me with 3.5gb of ram... so in reality i only upgraded 1.5gb. I just want to be sure i dont have any 'weird' processes running. I just cant see where all of this usage is coming from, when doing the basic math.
    I attached a link so you can better see what i'm talking about.
    Thanks again for your time.

  • Time Machine creates huge wired memory

    I have external FW drive attached to MacMini serving as home server. Mini is running Snow Leopard. Other three macs in our family are making TM backups to drive connected to Mini.
    But then strange things start to happen. Wired memory start to grow and after two weeks wired memory of mini is the size of 1GB. And machine becomes unresponsive. I have eliminated all apps on mini and I am quite sure that TM backups are somehow clogging the memory.
    Any ideas how to resolve this.

  • 'Wired Memory' issue

    I have seen many of this same problem before and had it labelled a kernel memory leak. Basically at activity monitor it shows a list of different 'types' of ram in use, wired, active, inactive and free ram. I have a total of 2GB ram but the wired memory takes up a very large amount of ram, around 850mb, and slows my mac down substantially. Even after all applications have been closed leaving only finder open, the wired memory still remains at this size. What is taking up this much ram? At start up it would be at around 100 - 200 mb then after a couple of hours would shoot up to 800-900 mb, slowing my computer completely. I know that there may not be a solution to this problem since wired memory cannot be controlled since it is used by the OS but if anyone has any possible explanation or solution to this please tell me.
    Hopefully Apple will also see this post, diagnose the problem and update the operating system.
    Thanks

    Applications -> Utilities -> System Profiler -> Software -> Extensions
    should show all the drivers. When you select a driver the bottom panel may show a "Get Info String" which in many cases will include a company copyright.
    Most of the Apple drivers have "Apple" in the Get Info String. Hopefully some driver you are interested in, includes the authoring company name.
    NOTE: Many Apple drivers are Universal, which just means it includes both intel and PowerPC code.
    My mac also has other problems like a disappearing dock, shows a shadow and the reflection of activity like the dock does, when i turn of my magic mouse and use the keyboard shortcut CommandOptionEject to put it on sleep, the mac goes into sleep mode but leaves a display open, and freezes, so I can see everything that was there the moment the mac went into sleep on the monitor; basically a still screen, and when i press the power button, it does not wake from sleep and it does not respond to anything except holding the power button down to turn it off.
    This is not normal behavior.
    You might try installing Mac OS X over the top of your current install (you should have a backup just in case, as you never know what could go wrong; Carbon Copy CLoner, SuperDuper, etc..).
    This is a drastic suggestion. If that does not clean things up, you might consider backing all your stuff (maybe back it up twice because I'm paranoid), reformat your drive with Disk Utility, next doing a clean install, finally restoring your personal stuff from your backup (maybe letting the migration utility do this as part of the installation).

  • Wired memory counts up to 100%, how to find unknown process leaking memory

    Hi,
    On my Macbook Pro 2011, 8GB wired memory counts up to 100% over a period of 4-5 regular usage days. The more I use the macbook, the more wired memory grows until I have to restart again, otherwise the machine becomes slow because it uses the harddrive for memory. This is not normal behavior!
    Attached is a screenshot of the activity monitor. I'm not able to identify the process which leaks the wired memory.
    I had once an eyeopening experience: I was about to restart my macbook totally overloaded by wired memory but then I canceled the shutdown because of some reason. Some of the processes and programmes were already terminated and SURPRISE, the wired memory was down to 10%! The 8 Gb were all of a sudden shared by free, active and inactive memory, as it should be! So some process was terminated during shutdown which caused the leak and even freed all of the wired memory. I did work with the macbook for 2 more days without any memory problem. Once I restarted, the leaking problem started again.
    My gut-feeling says the hole problem started when I installed VM Ware Fusion a while ago. But I did a clean uninstall.
    The solution could be to identify the leaking process, but how should I do this? It is also not clear to me wether wired memory is real, virtual, private or shared memory displayed in the activity monitor. Is there any tool which identify memory leaks?
    According to g_wolfman, the only process with a hugh difference between real and virtual memory is the kernel_task and the many Chrome Renderer processes. I have always 30 tabs open in chrome plus Safari (Flash disabled). I'm not able to terminate the kernel_task of course.
    Is there any way to isolate the troublesome process? There is no save start mode like in Microsoft Windows possible? This would be the first think I would do, checking if the problem persists in save mode.
    Disabled every start login objects btw.
    See in the image the amount of wired memory compared to the processes which are active. This is NOT the smart memory management OSX is capable of.

    Any suggestion? Is my system doomed to bleed to death every 3-4 days, until memory went 100% red (wired)? I would expect OS X to be smart enough to indicate memory leakers. I really do not get it.
    I migrated the same settings and applications to my freshly installed (10.7.4) 2007 Macbook. There the majority of RAM is active not wired.
    The only big difference is: On my 2011 Macbook Pro was VMWARE Fusion installed.

  • Why is wired memory less than what's used?

    why is wired memory less than what's used?

    A whole lot of the stuff you use can safely be paged out and back again with impunity. Wired memory is memory that cannot be paged out to Disk.

  • How do i allocate more memory to my iphoto application? i am unable to add more photos to my library  i keep getting a pop up saying not enough memory in my application

    how do i allocate more memory from my hd to my iphoto application? i have over 80 gb on my hard drive, but only 1.7 gb allocated to my iphoto application & i am unable to add more photos to my library.  i keep getting a popup that says not enough application memory.

    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.

  • Low system memory issue - caused by Mail?

    While I was at work, my wife was using our iMac at home, and she said that a weird error dialog appeared this afternoon that asked her to quit applications, following which the system became unresponsive.
    When I came home I found that a lot of running applications were in a hung state (unresponsive and required a Force Quit) so I rebooted the iMac.
    I looked in the Console and saw that at 15:39:37 today two errors started repeating at an enormous rate - something like 5000 times per second for the next 5 seconds:
      12/02/2015 15:39:36.373 Mail[226]: *** Assertion failure in -[MCSocket readBytes:maxLength:error:], /SourceCache/Mail/Mail-2070.6/MailCore/Networking/MCSocket.m:469
      12/02/2015 15:39:36.381 Mail[226]: exception parsing IMAP response: trying to read/write concurrently
    ...then at 15:39:42 the rate suddenly decreases to only about 10 errors per second. This continued for a further 15 minutes, until at 15:55:22:
      12/02/2015 15:55:22.000 kernel[0]: low swap: suspending pid 226 (Mail)
      12/02/2015 15:55:22.590 loginwindow[797]: -[ProcessPanel(lowMem) initAsLoMemPanel] | Lo-Memory panel initializing
    ...then lots of errors like this:
      12/02/2015 15:55:23.000 kernel[0]: memorystatus_thread: idle exiting pid 999 [com.apple.MailSe]
      12/02/2015 15:55:24.000 kernel[0]: memorystatus_thread: idle exiting pid 1000 [com.apple.InputM]
      12/02/2015 15:55:25.000 kernel[0]: memorystatus_thread: idle exiting pid 269 [com.apple.intern]
    So it looks to me like the Mail app went haywire, the Mac ran low on memory, so OS X made some kind of "Lo-Memory panel" appear to handle it.
    A quick search in Google Images revealed that there is such a thing as an OS X low memory error - the exact text of which is "Your system has run out of application memory. To avoid problems with your computer, quit any applications you are not using". It displays a list of running apps so you can quit them. The error looks something like this:
        http://i.imgur.com/HDplIwv.jpg
    When I showed this picture to my wife she said that is exactly what she saw.
    I will report this to Apple on their feedback page. If anyone has any other suggestions let me know. Obviously something that can bring down the entire system like this is not good.

  • Why is my Macbook pro getting out of RAM memory?

    I am getting a message that tells me i am out of memory and it gives me an option to quit apps i have opened, most of times it's just Safari and i have no idea why is this happening suddenly, i have Mavericks 10.9.4 everything updated, and a 15 inches Macbook pro 2.3 GHz Quad-core 4 Gb-Ram.
    Sometimes it gets out of memory just surfing on Safari, checking mails, or chatting on Skype, what could be wrong?
    I had upgraded to the public beta of Yosemite but i couldn't stand it and formatted my computer again and downgraded to Mavericks, but i don't know why i feel it slower now compared with the last time i used it with the same Mavericks version. i hope this doesn't delete my question since i am not revealing anything about the beta.
    Please any Help!

    Get rid of "Memory Clean." It's worse than useless.
    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.

  • OSX inactive memory management problems

    On my 2010 Macbook Air 11" running OSX 10.8 Mountain Lion, I have run into some major issues with memory management. This problem persists across both my Mac machines and multiple generations of OSX. I have a 2007 2.2 Ghz Core 2 Duo Macbook Pro Running Lion (upgraded from Tiger) with 3 gb 667Mhz DDR2 RAM and my 2010 Air 1.4Ghz Core 2 Duo (Upgraded from Snow Leopard to Mountain Lion) with 2gb 1067mhz DDR3 RAM. On both machines, for some time now, during normal usage; especially web browsing using Chrome and Safari (respectively); the inactive RAM on both machines will grow to consume around 30% of all RAM and force time consuming page outs to the mass storage drives on both machines. The Pro has a slower hard drive and the problem is the worst here, the air has a much faster SSD. I have found myself constantly having a window of Activity Monitor up on at least one of my desktops watching my RAM usage, using terminal to purge ram upwards of 10 times an hour to prevent costly page outs, especially on the Pro. I know Apple claims that inactive RAM is essentially free RAM that is temporarily storing recently used information for ease of access later and that it's supposed to be released as free memory when needed, but this obviously is not happening. Right now on my air my swap file is over 650Mb and I've seen it top 2Gb before. The air is exponentially better than the Pro due to the faster SSD, but I do notice substantial UI lag and a massive drop in fluidity as soon as my meager 2Gb is full and I start paging. The Pro is another story entirely, the entire system will essentially become unusable, having to wait several seconds for mouse clicks to even register. That's why I upgraded the stock 2Gb of RAM it comes with to 3Gb hoping that a 150% increase in RAM would help, but it just prolonged the inevitable. I still end up paging out just as bad across both systems if un checked. Even when I keep a close eye on memory usage and purge often, I still end up paging out because I'm not vigilant enough.
    I have to limit my browsing to less than 5 tabs and keep my number of open programs less than 2 on both machines. My active and wired memory rarely seem to top 70%, meaning the rest gets taken by inactive, which isn't functioning as Apple claims. Even if my conclusions aobut what is happening under the hood are incorrect, something is going terribly wrong. I can't upgrade the RAM on my Air at all, and the RAM on my Pro is capped at 4Gb. I'm holding on upgrading because I don't think the excess hardware will solve this software memory problem. Whatever is happening is causing a serious drop in performance for me (yes I do know I have underpowered machines), but there has to be something I can do to speed performance. I've read about disabling the dynamic page file entirely, which just seems to crash the system when free memory is gone, and I've read about programs that claim to free memory. Those programs seem to work by taking a high priority in the process heigharchy of the OS and then proceeding to eat up large portions of RAM and releasing them as needed in an attempt to replicate the true intentions of inactive RAM, but I've heard of problems with this method as well. Does anyone have a viable solution? Monitoring my RAM usage myself and ensuring I don't end up paging out is costly, time consuming, annoying, and inefficient since I fail to catch the problem before I page if I get particularly busy. There is no other OS I've ever been acquainted with that has this problem, not any flavor of Linux, not even the dreaded windows. I seriously hope Apple can do something to manage this runaway memory problem. I'd like to be able to open more than 3 windows in Safari. I've had to purge 3 seperate times while writing this on my Air, and I now have 678 inactive memory, 741 inactive, 582 wired, and less than 14Mb free out of 2Gb with a growing swap at 680Mb. Each purge becomes less and less effective and the last one I did freed up only about 100Mb and it got eaten up again by inactive in less than 10 seconds. On my Air, the memory hog is Safari right now at 700Mb between the web content and flash player with only Facebook, youtube, and this Apple Supprt tab open. I have NO other applications running in the fore or background other than Activity Monitor and Terminal. On my Pro the memory hog is always kernel task, I use Chrome and Safari both. While the memory used by the browser does not usually take up the most substantial portion of the total used RAM out of any process, the more tabs I open, the more RAM I use. The browser is usually the second heaviest RAM hog to Kernel Task. So it seems that across the two machines there are two lsightly different manifestations of the same problem with the same results: massive performance drops and extremely annoying and costly page outs no matter the reason. I just want this problem to go away. I've used underpowered windows laptops that can open a dozen tabs in a heavier browser like IE or Firefox while using other programs like Word or Excel and more with no memory lag issues. There's no way in **** I could manage to open that many pages in a browser while using Pages and/or Numbers on either of my machines and expect reliable (swap free performance). This is just kind of sad in my opinion. Does anyone have a way to get my OSX machine running smooth so that I can remove the one thing that windows and Linux fan boys get the right to laugh at my Macs for?

    Hi Zephryl,
    I was actually able to get an initial response from Sun on this a few months ago. However, the Sun Swing team has not followed up on a resolution for this pervasive problem, even though they noticed the same problem when running a test applet I had created for them. Apparently, I.E. is not releasing memory from the heap.
    Below is a quote from a Sun rep. on this in an e-mail sent to me on Dec 4, 2002:
    "I suspected the leak is in the native code because the # of handles and GDI objects keep increasing but no obvious Java objects are left behind in the Java heap during page switch."
    So, until Sun and/or Microsoft work out a solution to this, anyone who uses I.E. 6 and applets for their UI seems to be in a lot of trouble.
    As a note, trying to invoke the Garbage Collector does not do anything, but generally a very small amount of memory will be released (like maybe 5-10% of the memory allocated for the applet).
    Cheers!

    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
    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.

  • Memory Leak in 10.6.7?

    After a few days without a restart, MacMini running 10.6.7 with 2GB RAM is currently showing 1.15GB or wired memory utilization with no applications open.  After a restart, this is around 100MB but as days pass without a restart, it creeps up to 1-1.2GB.  Any ideas?

    Have you tried sorting activity monitor by Real Mem or Virtual Mem? if so what are the top culprits when your running out of memory?

  • New iMac27" OS 10.9.4 runs out of application memory

    I have a brand new iMac 27" with 1TB Flash drive, 16GB RAM, i7 processor 3.5Ghz
    Although I only migrated the data files from an older iMac running Lion OS, I installed only a few apps fresh on the systems:MS office 2011, Skype, Chrome, Teamviewer and Firefox.
    It was running for several days with only Mail and Safari open.
    Time Machine was on for backup.
    Suddenly it gave an error that application memory was full and the computer needed to restart.
    This is odd.

    Seems odd that a brand new computer less than a week old would give this error.  Any suggestions?

    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.
