ITunes high cpu, CoreAUC problem

Hi,
Running iTunes 10.4.1 on a 2011 MBA and it's constantly spiking the CPU. I emptied my library, created a new library, tried another account, but the problem won't go away. I don't use any iTunes plugins.
I've sampled the iTunes process in activity monitor and I see many, many messages like these:
    +                               ! : | + ! : 7 ???  (in CoreAUC)  load address 0x7fff931d9000 + 0x5e6b64  [0x7fff937bfb64]

Anyone know how I can troubleshoot this problem further ?
Thanks !

I am having the EXACT same problem with my MBA 13" mid 2011 ( 128 GB i5 version ).
I can't find an solution for this and am pretty new to mac OS. Went back to the seller and he said i should format my disk and reinstall everything from a fresh OS copy. Tried it but it didnt fix anything. Went back and he said i should contact apple...
Also looked on the internet, and the problem isn't that common apparently...
Found some things about CoreAUC and i'm not sure if replacing it matters, because i already tried formatting it...
Hope someone can help!
Thanks in advance

  • MSI KT6 Delta LSR SATA to PATA High CPU Usage Problem

    Well recently I've switch to my one of my other motherboards on my network to a MSI KT6 Delta LSR, it was working fine after a reformat, but I notice a few problems and that is 100% cpu usage for SATA to PATA, and vice versa, which seems really crazy. Then my network card performance is ISDN speed sluggish, and I tested my line to be working 100% with another mobo. But when I put another NIC on the same mobo it suffers the same speed problems.
    Any suggestions? The rig is specs:
    Barton 2500+
    Antec QuietPower 350W
    200GB Seagate SATA HDD
    40GB Seagate PATA HDD
    ATI Radeon 7500 AIW
    Audigy 2 Value
    Realtek 8139 NIC
    MSI KT6 Delta LSR Mobo
    2x512 MB PC 2700 RAM
    Pioneer 107D DVD Writer
    LG 16X DVD-ROM
    56K Modem (A-open)

    Shouldn't say what I don't know about SATA, but since I found below, I need ask if VIA 4in1 drivers are installed, preferably while in SafeMode I say:
    http://www.google.se/search?q=cache:X6ewgPiIHYcJ:www.qdi.nl/cgi-bin/bbs/YaBB.pl%3Fboard%3DP4I865%3Baction%3Ddisplay%3Bnum%3D1074174096+sata+to+pata+cpu+usage&hl=sv
    I recently installed 160g Seagate barracuda 7200.7 drive on SATA port. (I enabled the Bios using Auto) I have a P4I865pea-6al mother board, with two PATA drives . When copying files between the PATA drives on ide ports, to or from, the SATA drive, I notice the CPU usage goes up to 100%, but when copying files from one ide drive (the PATA drives) to another the CPU usage is very low.  
    Is there a bios setting that will allow me to copy files from the SATA drive to the Pata drives using a small amount of CPU power, found when just copying between the Primary and Secondary IDE drives? I am using Adobe premiere pro, which uses a lot of CPU power, and the high CPU usage of the SATA drive crashes this program? Any help would be appreciated

    have you installed the newest chipset- and ide drivers ?

  • FMS 4 configuration / High CPU usage problem

    I am seeing extremly high CPU usage issues with the FMS 4 server.  It seems to be a problem with the FMS Edge process?  If you start and stop the service, the processor goes back to normal operations.
    Looking in the Windows Event logs I am seeing these errors:
    Bad network data; terminating connection : bad chunk version 104 on input stream 00000000077A2E80
    Also:
    Bad network data; terminating connection : (Adaptor: _defaultRoot_, VHost: Unknown, IP: , App: , Protocol: tunnel) : h o s t = % 2 2 % 2 0 % 2 D F O O B A R % 7 C e c h o % 2 0 % 2 2 % 2 0 S h a r e n a m e % 2 2 % 0 A e c h o % 0 A e c h o % 2 0 % 2 2 % 2 0 % 2 0 S o m e S h a r e % 2 0 % 2 0 D i s k % 2 0 % 2 2 % 6 0 i d % 6 0 % 2 0 % 2 3 % 2 2
    Can someone shed some light on what might be causing these issues?

    Hi
    Can you please provide us some little more environment information on this issue, like:
      - what were you trying to do when you saw this issue, if there was a live telecast or if that was a simple vod workflow?
    - What publisher application were you using to send livestream to FMS?
    -  were you also doing some kind of recording while doing live streaming??
    - In case of live streaming what audio/video encoding and bitrates was there in use?
    - how many number of connections were there?
    - What amount of cpu and mem usage was there (when you say very high cpu usage).. you can see it using task manager
    It will help if you can also share your fms logs (inside fms_install_folder/logs) so that we can see if something abnormal was going on there..

  • ITunes high CPU usage

    Every single time I delete or add any item to iTunes, the CPU hits 100%, sometime for over 45 minutes.
    - iTunes does not respond to 'Quit'
    - Everytime you 'Force Quit' it comes right back.
    - Tried shutting off Ping, signing out of iTune Store - nothing!
    - Looked at all similar threads and discussions, unfortunately nothing helps, you just have to wait it out.

    Quickly doublechecking something ... you've tried disabling wireless syncing?

  • ITunes, high CPU, cant sync photos to iphone4!

    iTunes is hanging/freezing when i try to loade pics to iPhone4, and using 98-100% CPU! HELP!! it stops right before finish! tried 4 times now..

    Im running Vista and it's doing the same thing.
    If you really need to sync your phone, you can.  Just de-select sync photos and hit Apply and itunes will sync everything else just not your pictures.
    Also, I read on forums something about reseting the winsock in the command Promt, that did not work to sync photos.  I am able to connect to itunes store though as some people said they were having problems with that.

    Hello Dong,
    You are having a bridging loop. Check the devices connected on gi5/4 and gi2/5
    Show cdp neig gi5/4 deta
    Show cdp neig gi2/5 deta
    Once you know what our neighbors are, go on our neighbors and issue the following multiple times:
    show mac-address address 00:0C:29:60:42:BF.
    You have vmware and dell vendors involved. Check for nic teaming on the vmware side.
    You should see this MAC being learned on the interface connected to gi5/4 or gi 2/5 sometimes, and another
    interface the other times.  Once you know which ports these respective switches are learning the MAC from, issue
    the 'show cdp neighbor' and do this again.
    Eventually, you should get to a pair of ports that aren't connected to a switch, and only have this MAC learned. 
    Once you have these ports, you should be able to figure out what kind of devices these are, and why they are sourcing
    traffic from the same MAC.
    You can enable to debug command to identity the top interfaces that send traffic/packets for CPU processing.

  • Flash Player High CPU Usage problem

    When I used Flash Player on Windows XP, it used 50-80% CPU Usage so my browser was really laggy but when I used Flash Player on Windows 7, it only used 10-20% CPU Usage... It happened when I load same content on a website.and on same PC (I'm a dual boot user), so I think it's not computer specification problem..
    Could someone help me? Thanks in advance.

    First go to http://www.adobe.com/software/flash/about/ and check that both XP and Vista have the same version of Flash installed. Then check that both have the same video driver version as a more recent driver may mean more hardware acceleration is supported.

  • Q180 High CPU Usage Problem

    My new Q180 is showing CPU usage of at least 40% all the time in the Windows 7 Task Manager. Sysinternals Process Explorer show that this is due to over 25% of Hardware Interrupts happening all the time.
    Is anyone else seeing this kind of problem / symptoms?
    Solved!
    Go to Solution.

    I was able to locate and fix the problem yesterday. The problem was in the Realtek ethernet drivers. I disabled the device from the control panel and interrupts went a way. After that I removed the existing driver and re-installed with the one available on Lenovo support site and now interrupts are gone and CPU utilization is 0% when the computer is not doing anything.

  • [AfterUpdate] Psi unresponsiveness and high CPU usage problem

    Hi there
    I tried to look for a solution of my problem on the web but apparently can't find anything on the topic.
    I have just upgraded system via powerpill -Syu

    [2009-03-13 16:36] upgraded util-linux-ng (2.14-1 -> 2.14.2-1)
    After the upgrade everything seemed to be fine, but just when I try to write to anyone in the chat window of psi, processor usage increases up to about 97% and psi becomes dead. It doesn't react to anything but SIGKILL.
    I am using psi-git form AUR.
    I have tried to rebuild the package but it didn't work. So for the moment I had to temporarily switch to psi from extra repo. Nevertheless it would be nice if I still could use git version.
    Has anyone encountered similar problems?  Does anyone know which package is responsible for this strange behaviour? Is it psi itself (I doubt it because before update it was working well and it wasn't updated) or some kde lib?
    Greetingz

  • Attn: ALL APPLE PORTABLE OWNERS -Macbook Pro, MacBook Air Apple portable slowdown / kernel high CPU solution

    Attn: ALL APPLE PORTABLE OWNERS -MacBook Pro, MacBook Air, Mac mini slowdown kernel / high CPU use problem and solution.
    YOU COULD FRY YOUR COMPUTER IF YOU DO NOT FIX THIS PROBLEM SO PLEASE READ THIS ENTIRE MESSAGE!
    YOUR MAC WILL THANK YOU  
    Hey all.
    Like many of you I've got a newer Apple portable which slows down to an unusable level for an unknown reason. In my case a 13" mid 2009 Intel MacBook Pro Core 2 duo laptop. After many failed attempts to figure out what this nutty problem is I have discovered the problem, the solution and I have solved this for my own MacBook Pro. Since this fix it has been working immediately and consistently -without issue 
    I am sharing this with you in hopes that you to can fix your Apple portable yourself or so you know what to tell the Apple techs so they can quickly fix your Mac from this wacky and unfortunate kernel CPU hogging problem.
    User Software Symptoms :
    Your Apple portable computer periodically for an unknown reason slows down making everything frustratingly slow. This happens even when running previous apps that were never a problem; things that your Mac should be able to handle easily but for some reason now it can't.
    Slowdown most often happens during high CPU use such as gaming, video playback/editing, etc. or when running multiple apps (even non CPU intensive apps) at the same time.
    Possible Hardware Symptoms:
    Your computer is making more noise than it did previously.
    Your computer occasionally makes more noise but then gets quieter.
    Your computer is always extremely quiet (too quiet) even during high CPU apps -worst case scenario.
    It feels hotter than it normally does. Test: After several minutes of the slowness/high kernel CPU touch the computer to feel if it's hotter than normal.
    Looking at Activity Monitor (in the Utilities folder) shows the kernel_task is going bonkers eating up CPU but you have no idea why.
    After trying many different things to solve this problem such as :
    PR ram reset, SMC reset, fresh OS install of 10.5 and 10.6 on external hard-drives, calling and speaking to various Apple tech people who had no ideas/solutions, etc. I had no luck.
    Btw, if you're having the symptoms I've decscribed above I would not run the Apple Hardware check (read below as to why). You could fry your Mac!
    After much testing I found the problem :
    It is my belief that "recent" Apple portable computers are using low quality internal fans which soon stop working!
    Fail time period seems to be about 1.0 years to 2.5 years of use but this fail rate could vary depending on use.
    First noticeable symptoms (depending on what you notice) could be computer slowdown or your fan is making more noise than it normally does. This is your fan's lubrication slowly eroding making your fan spin slower and less smooth resulting in the louder noise and slower rpm spin speed. The slower fan spin speed means less cooling is happening for your computer. The effect on your computer is that the CPU and other chips are heating up! Overheating to be more specific. When your computer's chips overheat they get wonky and screw things up. Most often this seems to have the effect of making the kernel hog CPU resulting in a frustratingly slow user experience! Heat kills computer chips and it is extremely bad for them. Extreme overheat or repeated overheating has been said to shorten the life of computer chips or in extreme cases even fry them completely!
    The longer this goes on without being fixed your fan loses more lubrication and spins slower and slower cooling lesser and lesser resulting in your CPU heating up more and more possibly shortening the life of your Mac! Eventually your fan will stop completely and you could fry your chips! My fan stopped completely and my MBP was running very quietly, too quietly. Luckily I did not fry my chips because I was avoiding using high CPU apps because I knew something was wrong due to the massive slow down and wonkiness when I'd run them.
    Side Note:I'm a bit concerned about all those Mac mini servers which may be using the same defective low quality fans which cannot be easily serviced by their owners as they are co-located in some server facility. One positive thing is those facilities are usually well airconditioned keeping temps low.
    I suggest you do not run the Apple hardware test if you suspect your computer is overheating because the hardware test can seriously heat up your Mac! I tried running this test and my Mac got so hot I had to shut it down forcefully and I was concerned I damaged the chips. If you want to run the Apple hardware check make sure your CPU temperature is ok and that your fan works well before you run the test.
    IF YOU DON'T FIX THIS PROBLEM YOU COULD FRY YOUR COMPUTER DUE TO HEAT DAMAGE!
    DO NOT IGNORE THIS PROBLEM YOUR MACS LIFE MAY DEPEND ON IT!
    First you need to properly diagnose this problem and see if your CPU is getting to hot and you need to see if your fans are spinning at high rpms giving proper cooling, or if they are spinning at low rpms when running high intensive apps as your CPU temp increases.
    TEST IF YOUR FAN(s) IS WORKING CORRECTLY :
    Unfortunately Apple does not include CPU temperature reading software nor fan rpm speed software that I am aware of.
    However, There are two free ways that I know of to check your CPU tempurature and your fan speed :
    One app shows fan speed, and CPU heat, etc.
    One app shows fan speed, CPU heat and allows you to adjust your fan speed settings.
    One app is a dashboard widget, the other is a system preference.
    I suggest you download both of these to check your computer statistics.
    http://www.eidac.de/?p=134
    http://www.islayer.com/apps/istatpro/
    http://fan-control.en.softonic.com/mac
    I am not exactly sure what proper CPU temperatures are for the different Apple computers and this will change given different CPU loads.
    My MBP doesn't seem to function properly with anything around 90 degrees or higher (celcius).
    It seems when the fan is operating normally the CPU temp should not stay above 78 degrees even under heavy load, at least with the apps I'm running in the room temperature I'm in.
    I can post back later with more specific temps under longer load, etc. but I wanted to get this post up for people to read as soon as possible so they don't fry their Macs.
    If a bad fan is your problem :
    THERE ARE ONLY TWO SOLUTIONS FOR THIS PROBLEM :
    Fix or replace your fan so it cools the CPU and other chips properly.
    I fixed my fan myself and I didn't need to buy a new one. Total cost was about $8.00 because I had to buy a #00 sized screwdriver and had it shipped to me. Price includes shipping.
    On my mid 2009 model MacBook Pro fixing the fan was incredibly easy :
    Before I started doing this I wasn't 100% this was the problem so I decided to try to fix my fan instead of ordering a new one and replacing it. As it turns out I didn't need a new fan, I only needed to clean the existing fan and relube it's axl so it could spin easier like when it was new.  It also didn't make sense to buy a brand new fan from an Apple authorized parts reseller selling me the same low quality fan for $49.00 which would probably fail in 2 years again. Prices for new comparable fans from different manufactures range from about $15.00 USD + shipping to around $49.00 USD + shipping depending on where you order them from and what brand you get.
    How to fix / replace your internal fan on a mid 2009 MacBook Pro :
    Please note : I am not a hardware technician, nor expert. If you decide to fix your Mac yourself you do so at your own risk through no fault of my own. Prior to opening up your Mac you should google around and learn how to do it correctly and safely so you won't damage your Mac. For example, it is possible for you to damage your Mac by static electricity from your body. To avoid this I believe proper procedure is that you wear a 'ground strap' (around your wrist) which  you clip to your Mac's metal body so your body will not excude a charge into your Mac. I believe the idea here is to keep your body's charge level and your Mac's similar. Since I do not have a ground strap and fixing/replacing the fan doesn't require touching any chips I did not wear a ground strap during my fan fix. What I did was periodically repeatedly touch the metal case of my MBP hoping that would be enough and it was. Avoid unecessary actions that can build up a static charge in you. Once I started the repair I did not walk around the room building up an electrical charge in my body. Walking on carpet can often build up a large charge in us so it is better to be avoided while working on your Mac. Certain clothing can build up static charges. Combing hair, etc. If you need to get up from your repair when you come back make sure you first touch the Mac's metal case and not anything inside.
    Now that we're done with the scary paranoia, below you will find some instructions on how I fixed my MBP's internal fan
    Before you begin:
    Check out someone's video (not mine) on how to remove / replace the fan (but not take it apart and repair it):
    http://www.youtube.com/watch?v=AghE9newvbs
    Check out someone's web page (not mine) on how to replace the fan in a mid 2009 MacBook Pro:
    http://www.ifixit.com/Guide/Installing-MacBook-Pro-13-Inch-Unibody-Mid-2009-Fan/ 1338/1
    How to repair your mid 2009 MacBook Pro fan:
    Make sure you are in a 'secure' environment. No pets, no kids running around, no drinks near the Mac, etc. 
    Make sure your computer is unplugged from it's power supply and turned off. NOT slept. Totally off / powered down.
    1. Get a size #00 phillips screwdriver (Hobby store, Radioshack, Amazon).
    2. Open up your MBP by unscrewing the bottom (yes flip it over so it's resting upsidedown). Note where each screw goes because some are different lengths. I placed each one around my MBP where they go, insuring I know their order (don't jumble them up). Note which direction your MBP is facing when it's upside down so if you spin it around while working on it you still know where the screws go.
    2b. Some recommend removing the MBP's battery but I didn't do this step. You probably should, just to be safe. Follow the online instructions from the web page I listed about disconnecting the battery.
    3. Unscrew the fan's 3 holding screws.
    4. Unplug the fan's electrical connection (lift it straight up off the board). If you need to you can try to pry it up while you lift with a non metal/non electrical conductive object like a spudger if you have one or -perhaps a pen cap. Before you remove it, look closely at how it's attached so when you put it back on you won't wonder if you're doing it correctly. There's only one way it can go because it cannot fit 'the wrong way' but looking at it closely will make you feel more confident popping it back on when the time comes.
    5. Remove the fan - it easily lifts out.
    6. Take the fan apart by unscrewing it's one screw then unlatching the  plastic clips which hold it together.
    7. Seperate the fan blades from the housing. Lift the fan blades off of the fan housing by pulling it straight out away from the housing.
    8. Clean off the dust that's gathered. A can of compressed air helps here (I didn't have one). I used a little brush from my electric shaver kit which worked well. Once you've removed all the dust from the fan and surrounding areas proceed to the next step.
    9. Reapply new lubrication. You need less than 1 drop. Be sure it covers the entire fan blade axl as this is what needs to be well lubricated. Make sure there isn't excess oil that will fly around when the axl/fan spins at high rpms. I used the only oil I had which was olive oil (for cooking!) but I do not suggest this. At the time I was doing this I didn't know my fan was the problem so I wasn't even sure I was going to relube it. You should probably use something more appropriate perhaps like 3 in 1 oil. A good idea would be to call the manufatures of these little fans and ask them. Maybe a hobby store knows of good lubricants for these purposes?
    DO NOT use things like WD 40 as it's not a long term lubricant or so I've read.
    10. Once your fan is now clean and oiled (make sure there isn't too much oil) reassmble the fan.
    Push the fan blades/axl back into the housing shaft. Give it a few spins with your finger.
    Screw together the fan housing then reclip the clips.
    11. Place the now reassembled fan back into your Mac and screw it in place (3 screws).
    12. Reattach the fan's electrical wiring by gently pushing it into place. Make sure you've got the right end facing down before you push it in place.
    13. Once your Mac's internals are clean and reassembled, place the rear cover back on your Mac and screw it in place.
    14. Double check you didn't forget anything like screws, tools, etc.
    15. Boot up your Mac and monitor the temperature and fan speed using those programs.
    Compare the previous temps/fan speed to the current temp/fan speed.
    Run a high CPU intensive app where your computer has been slowing down.
    You should now have a happy Mac
    If you have this problem and this solution fixed it for you please post in this thread letting me and everyone else know!
    Hope that helps.

    Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

  • High CPU usage when playing flv files with flash

    As more and more FLV videos are moving to HD, I'm noticing
    high CPU usage and lots of dropped frames when playing FLV video in
    web browser with Flash 10. This is true even if the video isn't
    full screen. I've tried a variety of browsers (Firefox, I.E.,
    Chrome) and the problem occurs on all of them so it's pretty clear
    it's a limitation in Flash.
    Now my PC isn't high end (it has a Pentium M 1.86 GHz
    processor), but I can take those same FLV files and load them in
    something like Media Player Classic or Windows Media Player (when
    using ffdshow) and play the FLV files full screen with little or no
    drop in frames and an acceptable CPU rate.
    This is especially annoying on sites like YouTube where I
    actually have to save the video and play it back in something other
    than Flash to have it play back at an acceptable rate. This doesn't
    work for other sites like Amazon.
    Why is the CPU usage so high when decoding and displaying
    videos when compared to other media players?

    I've been doing research about this excessively high CPU usage problem (100%!) for weeks because I have also experienced it with my vista home premium laptop. Just recently, I have finally found the solution. The problem is not your browser or your OS or your pc's memory. The problem is caused by authorization for flash player.
    Read the link (posted below) carefully and follow the steps accordingly. If you have already done steps 1 through 6 with your computer, you can go straight to step 7.

    PS: I am not the author of that link, so please thank the respective site owner if you find the procedure very helpful.
    Please let me know also if the link solves your problem. I am sharing this because Adobe seems unable to provide solutions to this, and I don't want to hear people suffer.

  • High cpu usage when the system is idle

    I do have a high cpu usage problem when the system is idle. I bought the laptop (lenovo x230 tablet) with windows 7 installed in it. Then upgraded to windows 8. But ever since I have problems with high cpu usage by the system even when the computer is idle.
    Only the system by itself uses around 30% of the cpu all the time. I ran xperf, and here is the result of it:
    http://sdrv.ms/Kj6CFN
    I appreciate any help you can provide.
    Thanks,

    Hi,
    I'm sorry for that the log you provide can't be opened on my computer. While according to your description, it should had a special process that consume CPU usage when system idle Iguess, isn't it?
    You can use
    Process Explorer to monitor the process activity, may be we can find the reason of this problem.
    Note: We can use Process Explorer to check the Stack of every process then analyize the problem in deep.
    To gave a better insight about this problem, you can take a ScreenShot for this problem and provide the picture here.

  • ITunes 10.6 has High CPU Usage when switched to Mini Player

    iTunes has high CPU usage when switched to mini player. The CPU usage goes to 80-100% when the next song is played in Mini Player. iTunes then stays at high CPU usage.
    Upon exiting mini player the CPU usage will drop back to the normal 0-5% levels.
    This only happens when playing from the main music library; which my library is at 7089 items, 42.04 GB.
    When playing from a smaller playlist such as a smart playlist with about 15 songs in it for example, the CPU usage stays low/normal.

    Do you have any better luck with that if you update to iTunes 10.6.1.7?
    From the notes for the release:
    iTunes 10.6.1 provides a number of improvements, including:
    • Fixes several issues that may cause iTunes to unexpectedly quit while playing videos, changing artwork size in Grid view and syncing photos to devices.
    • Addresses an issue where some iTunes interface elements are incorrectly described by VoiceOver and WindowEyes.
    • Fixes a problem where iTunes may become unresponsive while syncing iPod nano or iPod shuffle.
    • Resolves an ordering problem while browsing TV episodes in your iTunes library on Apple TV.
