OS X 10.5.6: High RAM usage corrupts Audio Playback and Volume Control

Software Effected or Related:
iTunes 8.1, Quicktime 7.4, Adobe CS3
Description:
Basically any RAM intensive operation seems to corrupt the sound driver so that static is injected into the stream. In addition, volume control fails to function, with decrease of volume controls resulting in a louder more corrupted signal being sent to the speakers.
Attempted Fixes:
RAM swapped, no effect.
Permissions repaired, no effect.
PR Zapped, no effect.
Reinstalled OS, no effect.
Workaround:
It's in no way ideal, but once the corruption occurs, a reboot of the machine will restore function until the next RAM intensive operations causes the problem again. It's at best an annoying band aid.
Notes:
I'm not really expecting a solution, more as I want to find out if anyone else is having a similar issue to my own. If this system behavior sounds familiar, please reply and let me know about your system. This behavior only started for me when my company migrated to OS 10.5. A downgrade is not an option, due to software compatibility issues. Thanks for your attention.

I am having that exact same issue with my new MacBook Pro. I notice faint bursts of static like the audio is trying to break through and then it is lost all together. I trash my sound prefs (both Library/Preferences and ~/Library/Preferences and reboot which corrects it, but then it happens again within a few days (or hours)... what gives? What is corrupt and what file do I need to permanently replace? Do I need to call Apple about this on a new machine?

  • MSI GE70 2OE, high ram usage problem

    Hey,
    when i start my notebook everything goes fast and runs normal. but after a few Min's working with notebook my RAM usage goes up to 95-97%, and everything goes slow.
    not running any special programs that can use so much RAM. and can't find anything in Task Manager what it could be.
    Normal RAM usage:
    High RAM usage:
    can anyone help me with this? thx

    I'm currently trying to help my friend with this issue... But worse.
    He had the same issue happen to him. Brand new GE70, got it like a week ago. RAM maxed out, but task manager didn't show anything near that much being used by individual processes. Shortly after he said this he also said the disk usage had gone up to 99% or something similar.
    The laptop became completely unresponsive and he had to do a hard reset - but it won't boot up anymore. Just flashes the MSI logo for a moment. Once it got to a screen that said "preparing automatic repair" for a second or two before shutting off again.
    Tried EC resets, no dice. Got him to burn a copy of hiren's boot cd to try and run a disk check, it didn't even get to checking the drive. Now the power button doesn't even light up.
    He's spoken to MSI support, they said to send it in... But he's got some data on there he needs and can't exactly get on to recover it. It's a real pickle.
    So... uh... make sure you have backups.

  • [SOLVED] Arch64 high RAM usage...

    I recently installed Arch64 on my MacBook and everything works fine, however I noticed its using very much RAM in comparison to my 32 bit workstation system (which has 4GB, not all seen o/c in 32 bit, while my laptop has only 2GB). Right now, with only X, musca, firefox and 3 urxvt terms open its using about 25% of it. which comes down to about 500MB. I didn't mind that much until just now I've seen it going up to 64% after I've launched matlab and it remained at this number after I closed it. My system is still responsive and fast, but I'm afraid I'm running out of RAM quite fast this way...thus if this cannot be explained or fixed I'm forced to go back to Arch32.
    Is anybody else experiencing this ? I'm running kernel version 2.6.33.4-1 btw, and xorg 1.7.6-3.

    Unused RAM is wasted RAM.
    And firefox is KNOWN to be a memory grubby hog.
    Let the kernel do it's job. Unless you are specifically having issues(100% ram usages and high swap usage) there is little to worry about.
    Also relating to Arch32 v Arch64.64 has a larger memory address(64 against 32) apps will use more RAM.

  • Mid-2012 MBA Battery Life + High RAM Usage

    I recently purchased the lastest mid-2012 base model MBA brand new, factory sealed from eBay and started using it a few days ago. Overall its a great machine, however there were two things that were slightly bothering me;
    1) Although the battery life is decent (around 5.5- 6 hours), on the system report page (see pic 1) , it said it only had 6128 mAh of charge remaining at 99%, even though the full battery capacity was 6527 mAh. Does this mean the battery capacity has already decreased after just 3 cyles or is this normal with lithium ion batteries? However, I don't know if this matters, but the place where I'm from suffers from frequent power cuts so I had charged the computer on a sine wave inverter a couple of times (AC current line). Could this have affected it in anyway?
    2) The computer had shipped with OS X 10.8 and I upgraded to 10.8.2 the same day I started using it. While the computer doesn't feel sluggish at all (well, tbh I haven't run any heavy programs yet), even with very few of apps open, the RAM usage is very high (see pic 2)- It says I am using 2.92 GB of RAM, and have just 1.07 GB of free RAM. Is this a common problem in with ML? I was planning to install VMWare and CS6 but now I'm not too sure judging by the amount of free RAM I have atm. What should I do about it?

    Would highly appreciate if any of you guys could help me out here. Thanks in advance !

    I'm at 1.02 GB of wired RAM on a completely "naked" boot of OS X. I've got zero 3rd party apps installed or set to launch it's all core services of the OS only. Oddly enough, my 13" rMBP is at 1.18 GB off the same basic boot on 10.8.2 so it'll vary a little.
    I also find that with Mt. Lion the reporting is on "tape delay" as I jokingly call it. For example when I start up an application it'll use "x" RAM and then after 5-10 minutes of just idling it'll then level out at "y" RAM. Where you have to be watchful is on 3rd party applications that will sometimes just start consuming RAM like that's it sole purpose.
    On a side note, I've been fooling around with a free application on the App Store called "Memory Clean" that's suppose to take previously allocated RAM and free it up. So far so good, it's especially handy after I run a handbrake job or play some World of Warcraft where a significant amount of RAM is used. Definitely not a required application, OS X by default is quite good at freeing up and reallocating RAM but sometimes it doesn't always get the job done if you need it right now (for a VM).
    In your full charge capacity photo the machine is running on battery power, although at 99%. On my MBA I get almost 280 mAh of usage between 100% and 99% that right there would close the gap considerably.
    On the subject of 3rd party applications, Coconut Battery (a free 3rd party application) has a handy tool that allows you to create data points on battery health. Might be worth exploring so you have a statistical representation of the battery's health if you're interested.

  • High RAM usage when system is 'idle' (EtreCheck)

    Hey guys,
    First timer here. Ok here's my question :
    I recently bought a secondhand Macbook pro 15 inch. For me it's a huge upgrade coming from a 2009 13 inch Macbook pro. Because a friend of mine wants to buy my old one I was doing some diagnostics on the 13 inch, which has 4 GB of RAM, and found out it had a lot of inactive RAM usage and wired usage, almost 2 GB, due to a lot of launchdaemons etc which were hogging the RAM. I used terminal to kill these agents and deamons and now that system is running smooth again. Maybe it's wise to mention that the 13 inch runs on ML.
    3 days ago I did a clean Yosemite install on the 15 inch, swapped the HDD for a SSD. And already the activity monitor shows a whopping 4,28 GB of RAM usage while I'm typing this with just safari open. I thought I could do the same trick as I did with my 13 inch but it didn't help, had some java deamons and helpers and deleted those. In terminal I looked up everything via launchctl list and there's nothing unusual going on as far as I can see. I had VirtualBox for one day but uninstalled it using their uninstaller. I have no clue what's eating all this RAM.  Please help me out so I can be a proud owner of my second macbook for atleast 5 years to come. Thanks in advance.

    The page outs indicate the OS has not recently swapped any memory to disk.
    Apple made changes to 10.9 that are the same on 10.10. Memory will be used as much as possible. It is the fastest storage on the system, keeping it free is a waste of your time - data loads fastest from RAM.
    This is a good explanation…
    http://arstechnica.com/apple/2013/10/os-x-10-9/17/#compressed-memory
    The system also frees 'cache' memory when another process has more need to use it. Eventually it will swap to disk (which is slow) so the OS also compresses memory before swapping is needed.
    Please avoid killing launchd jobs, many will simply restart or relaunch again later. Eventually you may kill one that hangs the OS & corrupts the disk via a forced shutdown.
    I do suspect you may see issues when RAM does get low, but there is no evidence of that here. The memory pressure graph will show red when swapping - every other colour is fine. Wait until you see red & then note the top memory users.
    If you don't want java installed you need to find removal instructions & get it all off the system, simply stopping the update checks will leave Java in an old state - terrible for security.
    Also do you know what 'Live' is? It crashed recently, if it keeps doing that it may be worth a look, however it may just be one if the things that was effects by the killing spree

  • Kernel_task high RAM usage

    Hi everybody,
    I have same problem on both iMacs i use (iMac9,1 and iMac10,1). Both updated from Maveriks to Yosemite some months ago and since last 2 weeks kernel_task "eat" to much RAM.
    I tried to solve with all kind of resets, move files from ACPI_SMC _PlatformPlugin.kext, hardware test, reinstall and restore from time machine and finaly also with a complete clean reinstall (without TM restore!). But kernel_task run with too much RAM usage.
    I feel frustrated and I seem to be back like Windows users!
    So, i think problem could be associated to some software upgrade (DropBox? Skype? Osx update? don't know). Anyone knows if there are usefull debugs system log for kernel_task usage?
    This is log from EtreCheck of iMac9,1

    On this report kernel_task ram is not displayed but you can see it on task manager image
    Any help is apreciated.
    Thank you!

    There is nothing wrong with your kernel_task memory usage.  It is consistent with the amount of RAM you have installed.
    The kernel_task manages virtual memory page tables.  The more RAM the the more table space consumed.  800MB memory usage for kernel_task is in line with having 8GB of RAM in your Mac.
    My 16GB Macbook Pro kernel_task has 1.15GB of memory.  People with 32GB Macs, have more like 1.5GB.  And Macs with 4GB have something around 500MB more or less.
    Tangent observation.  Unless you have a Paid LogMeIn account, the free version has been discontinued, and you should most likely remove the LogMeIn components via the LogMeIn uninstaller.  Your use of TeamViewer.com is a good substitute for the free LogMeIn.
    You system has been up for just 7 and a half hours
        OS X 10.10.2 (14C109) - Time since boot: 7:21:25
    But you have
        117.96 GB    Page-ins
    That averages out to 4.6MB per second.
    Chances are you could either benefit from not running as many concurrent things (maybe remove the large number of kernel extensions, launch daemons, launch agents you have installed), maybe only run VirtualBox when you really need to run Windows (assuming it is Windows, but I guess it could be Linux or Solaris X86), or have fewer tabs open in your web browser, or run fewer Apps, especially the big memory hungry kind)
    Or maybe you just need more RAM if you must have all these things installed and running all the time.
    Just a thought.  But it is not kernel_task that is causing problems.  That is normal.

  • [SOLVED] high ram usage

    Hi !
    I have the following problem . i 've installed kdemod3-base (the minimum edition) and when i boot the ram usage is about 300 mb ram . After a while , after using ktorrent or firefox my ram goes up to 950 mb and i have only 1 gb ram . this is what i get with ony konqueror open :
    free -m
                 total       used       free     shared    buffers     cached
    Mem:          1010        944         66          0         12        809
    -/+ buffers/cache:        121        888
    Swap:          972          0        972
    does anyone know what might be the issue ?
    thanks for your help!

    I hope you know that RAM is faster that HDD, so if you have a Ferrari (RAM) and a biiiig truck (HDD) and you want to drive really fast, which one will you pick? Sure, the truck can hold a ton (or rather several tons) of things, but it's not a speed daemon. If you have the Ferrari just standing in your driveway all day long you're not really using it right, right? On the other hand, if you use your sports car for everything but the toughest jobs (which require the truck), you can feel the performance you payed for - that's the cache thing.
    No offense, but maybe sb knows if there's such a thing as manpages for dummies? ;-)

  • High ram usage when loading high resolution images

    Hello,
    I'm wondering why Firefox almost hangs my system while opening high-resolution images like this one (save your data, you have been warned):
    http://minecraft.1favre.de/output.png
    While opening, it involves X process to use CPU and a lot of memory (it's freed shortly after loading the image). Other browsers don't do that. Moreover, other browsers don't do any problems with such images, they load it fast and efortless. I Have 2GB of RAM.

    Hello,
    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
    Did this fix your problems? Please report back to us!
    Thank you.

  • High RAM usage and gets hot?

    For some reason, the memory usage is always really high... Like over 3 GB without anything open. Sometimes it goes over to 3.5-3.7 GB. It still runs pretty fast I guess but there's considerably noticeable slowdown at times as compared to before this issue started.
    Might be that system stats thing...
    It didn't use to be this way and it also gets hot frequently.
    I heard of a method involving holding different keys while the Macbook is off and connected to a power adapter. Is this safe and is there any danger of losing files?
    On a side note, my battery status is "Service Battery", in case this might have anything to do with it...
    Here are some snapshots of my activity monitor.

  • Arch64 high RAM usage.

    Yeah, I do obviolusly know that arch64 uses more RAM than it's 32bit's counterpart, but i'm just still puzzled about the following:
    I've recently changed from arch32 to arch64 and where arch32 used 45mb when logged in to X(musca) and arch64 using 134mb. Both values is - buffers/cache!
    Well, I then just thought that it was the processes running that used so much ram, but after running ps_mem.py, htop and ps aux, then I can see that im using under 30MB.
    Then I thought that it was the kernel, but dmesg lists that it uses under 5MB.
    Then I thought that it was some kernel caching thinggy, but /proc/meminfo lists only 17MB under slab(and where half of that is freeable).
    Lastly I checked the kernel modules running with lsmod, and there where only a few which had big size numbers(radeon etc), and they were in the ranged of about 900000, which I would believe is in bytes and hence about 0.9mb, since if it where in KB, then it would be far too much, but additionally, then I read somewhere that lsmod uses number of pages for it's size values, but that dosen't add up, since then each of those modules would be using way to much, as each page is 4kb?
    I'm not at home right now, so I cannot post the exact values described above, but I have looked at them soo much, so that I know that the estimates above is correct, but I can still post them when i get home if someone wants to look at the exact values.
    Btw, I do have 4GB, so it's not about that, but I just wants to know where my MBs are spent in detail....
    Also, I have not added any extra demons, services, apps or anything and without starting X, then it's 116MB without buffers/cache, and where the exact same setup on arch32 used about 35!...
    I wish there where some kinda tool or script which could list kernel memory used and how much memory each kernel module takes up and such, as im at  a complete loss about where my used MBs are ending up... (yeah, I know that everything is allready listed in various files under /proc, but im not wise enough to analyze and make sence of that yet...)
    If anyone could give some input on this, then i'd really appreciate it!
    Thanks in advance!

    No prob; thanks anyways mate!
    @all
    The thing im requesting further elaberation on is this:
    free -m reports 134MB used without caching, but I cannot see more used than:
    ps_mem.py lists under 30MB used(total=private+shared). (and max 50MB if going by htop).
    dmesg lists the kernel to use under 5MB.
    /proc/meminfo lists slab as using 17MB(half of that reclaimable; I don't know how free -m deals with that).
    lsmod shows only 4 big modules(and many small ones) with sizes in the range of highest 900000, which I guess is about 0.9mb.
    That is maybe 60MB max and along way up to 134, so I am thinking that it's either some hidden kernel caching/reservation, or that the culprit is the kernel modules i.e.probably the radeon driver,but I don't know how to check that besides the size listed by lsmod, which dosen't show any big values, but the thing is also that I used the same driver on the I686 version and where the memory usage was at total 45MB, then im not sure that it's even that(unless the radeon driver uses many times more memory than the i686 version?).
    I wish I knew how to meassure these things in detail...

  • High memory usage from service host and chrome

    From time to time I get a low memory from Microsoft, warning telling me to close various open programmes (word, excel mainly). I also get 'He's Dead, Jim' when I try to open my chrome browser.
    I've checked the task manager and both Chrome and the Service Host seem to take up the most memory (currently around 96% used). Ive managed to get rid of it for short periods of time but then the warning keeps coming back. 
    How can I solve this?

  • ISE dashboard not showing CPU RAM usage for Admin/monitor and PSN

    Hello,
    I have a distributed deployment in pilot with one node dedicated to Admin/Monitoring and another dedicated to PSN.
    On the dashboard, (httping to the admin node) neither of the nodes show their CPU and RAM stats (appear as grey icon).
    logging to 20514 is pointing to the primary admin node.
    Does anybody have any insight?
    Have already resynched deployment with no success.

  • High kernel_task RAM Usage in Yosemite 10.10.1

    Hello All,
    No matter what I'm running, I always have high RAM usage with kernel_task. I've looked around the other threads and never found a definitive solution. I wouldn't call it crippling to my system but I would like to resolve the issue. Below is a screenshot of my activity monitor, and my Etrecheck run. Please let me know anything I can do to reduce the RAM usage of this process.
    Problem description:

  • MacBook Pro very high overall RAM usage

    Hi, I'm using a late 2012 13" MacBook Pro with 8GB of RAM and a dual core i7 and I've been experiencing very high RAM usage for the last couple of weeks even though I'm not really doing anything. Here's a activity monitor screenshot
    As you can see I'm only really using Chrome and Sublime Text (3). Twitter and Outlook are also open but don't take up that much (Twitter maybe but that just seems to be badly optimised and it's all gone when I close it).
    So, is this normal?
    Thanks in a

    This is normal. The two most important things in that screenshot are 'Swap Used' (0 means you never ran out of RAM) and the Memory Pressure graph (everything green = good). For the rest the OS knows to handle RAM,

  • OSX Lion ram usage

    Well, i've got my 13' Macbook Air today (4gb ram), and love it.
    The only thing that bothers me is the extremely high ram usage of Lion, when i turn the Macbook on it jumps to about 1.3gb ram usage which i find really much considering my PC running Windows 7 uses less.
    After some casual usage it even jumps up to about 2 gb ram usage.
    Is this normal? how are the other Air's with only 2gb of ram handling this? there can't be much left there, besides just running the operating system.
    i am new to Mac's so am i doing something wrong?

    Hi all,
    After last Lion update a i seem to encounter a very strange situation regarding ram usage.
    I have an early 13' mbp core i5 with 8gb of ram.
    After upgrading to lion 10.7.1 i have less than 500mb available after just a few hours since i turn it on.
    I must mention that the only running apps are: safari, mail, app store, ichat, ms excell and itunes.
    Upon quitting excell, itunes, appstore and restarting mail and safari i still only get 1,5gb of free ram.
    My suspicion is that there is another ram leak somewhere, or else i can't explain why my computer user 128mb of swap with 8gb of ram installed.
