Itunes takes 100% CPU usage ?

hi;
     recently I updated my iTunes to v10.6.1 and after the update iTunes started taking 50% CPU and another 48% went to AppleMobileDeviceService which made my computer painfully slow.
     i tried to fix the problem by completely uninstalling and reinstalling all of the Apple Inc. software but didn't help.
     can you help me fix this problem also is there any other information I need to provide ?
thank you

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

My laptop (win7 2ghz, 1gig) has 100% cpu usage with itunes installed (even when not running itunes) since the upgrade. i had to uninstall. tried installing but still the same problem. my daughter wants the new ipad, but this is a serious problem.

when itunes upgraded my laptop went to 100% cpu usage. only solution was uninstall. have tried itunes again as my daughter wants the new ipad. still same problem tho so not keen to spend £400 on new pad without pc support. anyone help? (ps been using ipod touches 1 and 2, been great source of pleasure for my two girls, but cant sync them, so using the little shuffles for music, syncing to an old version of itunes on an old netbook - had the sense to switch off upgrades when the new version went wrong)

100% CPU usage with XP Cooler from PCAlert4

Any idea why I would be running 100% cpu usage when running XP Cooler from PCAlert4? I noticed PC was sluggish when running it so CTRL+ALT+DEL and under performance is 100% CPU with 245MB Ram Usage. No other TSR's running - several application but under 10% CPU usage without PCAlert and XP Cooler.
I was also wondering if anyone had any ideas on the video? I have the K7N2G with 768MB DDR PC 2100 (3x256) XP2200+ 266FSB running 1804MHz - Maxtor 30GB 7200RPM - 350W PSU (raidmax - yea yea I know, dont say a word though LOL) on board video and here is the problem - graphics are great, but they get choppy - running NFS HotPursuit 2 at 32bit 800x600 (doesnt seem to matter even when running 16bit 640x480still does it.) what setting am I missing? Thanks in advance.

Deathstalker (Richard),
I did what you suggest in memory management and also changed out the mem on the board - it did make a difference, not as much as I had hoped, but it did.
Raven,
I have used Fraps in the past, forgot about it, but went ahead and downloaded it to get a better look.
To the Both of you,
Thanks so much for your replies, sometimes it just takes someone outside looking in to see the things overlooked. But I went ahead and also ran all of the latest updates for the board (semi new system and I only installed with the CD that came with the Mobo) and everything is running better than expected. Thanks again for your thoughts - keep 'em flowin, it's amazing whom we could help. Take care.

Music store & 100% CPU usage

I've had this problem on my newly built computer, and my older machine. When I browse the iTunes music store, the status bar on the top will often move like it's opening the music store, but it'll do this for a long period of time (several minutes) and iTunes will work, but the music store will not load, and you cannot click the 'X' to stop the contacting of the music store. During this time if you open task manager, iTunes uses 100% of CPU resources. If you close iTunes it still uses 100%. you have to end the process in task manager in order to make it stop. On occasion the music store will work to view maybe one album, but if you search for another album, or click another link it'll do the whole not-responding-100% CPU usage cycle again.
All drivers are up to date and like I said it's done this on two seperate computers of mine on the same iTunes account. I also have a laptop and the music store works completely fine on it. It's only on my desktops that I have this issue.
Some specs on my machine if this will help
Asus motherboard
AMD Athlon XP 4000+ processor
2gb Kingston 184 pin DDR ram
Seagate SATA II 160 GB HD
Windows XP PRO service pack 2
thanks for your help!

I'm only guessing here, but perhaps iTunes is having a conflict with another application. If you are anything like me you probably install your favourite applications on all your computers. As a shortcut to troubleshooting, perhaps consider an application you have installed on the desktops, but NOT on the laptop. Then try uninstalling that application from your desktop computer and test iTunes.

100% CPU usage by iCal

For some reason my iCal application uses 100% of CPU. What can I do to avoid it?

I had a similar problem with iTunes.
Here's the link to what fixed my problem immediately. Please note: my problem was resolved following just the three steps pasted below. The original link has additional steps that may be necessary, although I did not employ them, and my problem of 100% CPU USAGE is gone!!! Thank God!

Fuzzy Logic 4 & 100% CPU Usage freeze

Hi,
is there any Fuzzy Logic 4 Version out there that works with KT3 Ultra2-R and XP?
I tried 4.0.63.1 and 4.1.48.0 from the MSI Pages and the Version I got on CD
4.0.63.1 just can't find the avi ...
4.1.48.0 and the CD Version just add the Icon to the taskbar when starting and than take 100% CPU-Time and do nothing anymore.
The Program is not even killable in Taskmanager so all I can do afterwards is wait 10 minutes until XP has shutdown with the leftover CPUtime.

I understand the CS2 is probably not helping, but there is really a problem on other apps too - not only CS2 and those are universal.
Page ins/outs are currently 142257/71109 and i have not been using or even opening CS2 - just safari, itunes, What size , MSEntourage, VLC and moving some files.
I have taken some earlier advice on your posts regarding using multiple internal disks - so i moved itunes and iphoto libraries to a separate disk and also use that for scratch in CS2. The drives are 250GB WD and 250GB Seagate, and i am looking at replacing them with one or two 750GB WD RE2, although probably not in RAID ( dont want to complicate my life too much in one go !)
Overall i think the page ins/outs look high from my searching in other posts, but can't see why it would be overloaded when i normally dont use the CS2 that much ( only a hobby)
Also the private/var/vm directory has 3 swap files - two of 64 MB and one (Swapfile2) is 128MB, if that tells something else ?
looks like i will have to invest in 4GB more memory as well as the HDD's. i was confused with the apparent further lack of support in CS3 for 64 bit programming (?) although i dont know when that would be launched so soon after CS3
I have a case of a little knowledge ( which can be a dangerous thing!)

100% CPU Usage caused by HMI

Hi everybody:
I'm working with LabVIEW DSC 8.2.1 in a system that monitors many variables of a plant, such a typical SCADA system. For this reason, the use of the graphic tools is highly used on the development of this system. Everything works fine, but I have only one problem.... the usage of the CPU.
When I am working on the development system I (not the executable) I start the application and after the variables are initialized and every process has started and are running , the CPU usage is raised around 90 - 100%. After a few days investigating the reason of this, I realized thay when I change the view on the screen to another view, for example the block diagram of the application, while the application is still running, the CPU usage goes around 15 - 25%. I've tried these many times changing the view from Front panel to Block Diagram and viceversa and the result is always the same: Front Panel= around 100%; Block diagram or another view (other applications MMIs, or Block Diagrams, etc.)= around 20%.
Another thing that I realized is that the other view (different to front panel) has to fill the entire screen to work the way I'm telling before.
When I build and run the executable, the usage of the CPU is the same... (around 100%), but I can't see any other application, because the application built is the shell of the OS, so no other views are available.
I don't know if there's some other consideration to take into account about the HMI when creating an application, and I'll appreciate very much your help.
Thanks in advance!

From http://100cpuusage.blogspot.com/
100 Percent CPU Usage when you run programs after you install Windows XP Service Pack 2
CPU Usage 100% Symptoms
When you run some programs, the CPU Usage meter in Task Manager may indicate CPU Usage 100%. When CPU utilization reaches 100 percent, programs will run very slowly or stop responding (hang) and your computer is freezing or crashing.
Noteress CTRL+ALT+DEL to view CPU utilization, click Task Manager, and then click the Performance tab.
These symptoms occur after you install Microsoft Windows XP Service Pack 2 (SP2).
CPU Usage 100% Cause
These problem occurs because of the user interface code that is included in Windows XP SP2. The high CPU utilization is caused by the additional overhead that occurs when the IsWindow function is called by the user interface code.

Zenity takes 100% CPU Time

When I run as root or normal User
zenity --notification --text="test"
The zenity process takes 100% Cpu time
System:
Arch 32bit gnome 2.22
Last edited by brickwedde.eu (2008-05-06 11:26:00)

I GOT IT... I think.
zenity --notification actually calls libnotify! I was trying out a script and suddenly realized something, because by chance dbus decided to take a break. Take a look at these two code fragments.
$ zenity --info --text "hello"
$ _
$ zenity --notification --text "hello"
libnotify-Message: Unable to get session bus: Failed to connect to socket /tmp/dbus-jmMdFXbznS: Connection refused
<hang>
<100% CPU usage>
I've figured out why: it's basic socket programming gone wrong. The notification part of zenity calls libnotify, tries to connect to libnotify's socket, and fails, using 100% CPU waiting for the connection to... end a stream that never started.
A possible solution is to just use notify-send.

Queue consumer stops with 100% cpu usage

I'm trying to use Berkeley DB queue with transactions. When I tested what happens when transactions with DB_APPEND are aborted I found that while it works and DB_CONSUME correctly skips over rolled back records, unfortunately extents that have those records are never deleted, which causes database to always grow. Next I tried DB_CONSUME with database opened using DB_INORDER flag and it seems there's a serious regression in Berkeley DB that causes it to loop indefinitely with 100% cpu usage when it encounters a rolled back record. I tested various versions and found that this bug doesn't happen with 5.1.29, but it is reproducible with 5.2.42, so this regression might have been introduced in 5.2. I have also tested 5.3 and 6.0, and both have this behavior. There may be something wrong with the way queue records are rolled back, one indication of that would be that in 5.1.29 doesn't have neither of the two problems I found with DB_QUEUE: extents are deleted after being consumed, and there are no issues when consuming with DB_INORDER either.
You can find Python code to reproduce this issue here:
https://gist.github.com/snaury/027a3c546f5b0a62a440
Sorry for using Python and not e.g. C++, but it's a lot shorter that way.

We have looked at the issues and they are valid. We will roll the fixes out for this in our next release of BDB. The test case was very useful and really helped to speed the process up. If you have any questions, please contact me directly at [email protected] Thanks again for bringing this to our attention.

HP LaserJet Pro MFP M127fn - DNS issue, hundreds of UDP connections affects my router 100% CPU usage

Hi all,
We've bought about ten pieces (HP LaserJet Pro MFP M127fn), tested only one the other 9 are waiting for their time to be sent in our branch offices. The MFP works fine, no complains till later that day I noticed that our Mikrotik Router was struguling with high CPU usage, it took me some time to find the issue and it was the new bought MFP. Don't know why but it creates hundreds of UDP connections and almost 100% CPU usage goes to DNS service. As soon as I shutdown the MFP and delete all the connections everything goes back to normal. I've disabled almost all services (HP web service, Ipv6, SNMP, AirPrint, SLP, LPD, WS-Discovery, Bonjour), leaving only Ipv4 but without luck the issue persists. Here are some print screens confirming my saying:

Problem:100 % cpu usage with tcp server dll

Hello,
I am trying to write a dll with labwindows/cvi that allows me to create a TCP Server. This dll is integrated in labview.I created this Dll with example provides by Labwindows/cvi(rtserver.dll).
Description of my problem: when i execute this dll in a "While Loop" in labview,the TCp server wait a connection and 100% cpu usage occurs. However when a client is connect to the server,the CPU is normaly used because the program stop when he meets the timeout of the tcpread() function. I would like to know how i could limit CPU usage when the server is awaiting a client in the labview "While loop".
I know I could use a DELAY() to limit Cpu usage ,but I would like to know if there are any others solutions.
thank you.

i dont know your exact application, but i generally use Q to transfer data to TCP loop in my prgram it helps me in two ways.
1. it automatically restricts the iteration when ther is no data (Less CPU Usage, Less Unnecessary Trafic)
2. Q can eliminate problems arising due to non synchronization of loop

Distiller 8 and 9 both locking up, 100 % CPU usage

Not sure if its related, but probably, since it happened right after...I just transferred everything from my quad core mac pro to my new 8-core Mac Pro. Everything went well, but now Distiller 8 starts and then sits and gives the beachball of death, and one of the cores shows 100% cpu usage. (I have that utility that shows memory used, CPU usage, etc.). I hadn't bought Acrobat 9 yet so I downloaded it and installed, and Distiller 9 does the EXACT same thing. The ONLY thing I can call an "error message" is that I can see in the window after it launches is "Error in /Library/Application Support/Adobe PDF/Settings/PDFX4 2007.joboptions:/CheckCompliance out of Range."
That message may have been there whole time, even when it worked, though. I don't know. At any rate, I need distiller working! Any ideas?

Glad to hear all is well. Preference files can cause big problems. Eons
ago, in the 1980s, I used a communications program called Red Ryder. I
loved the program. After it was updated to a new version (it might have
been called White Knight by that time), I started to have terrible
problems. I wrote to their technical support. They couldn't duplicate
the problem. It couldn't happen etc. I eventually got a little hot under
the collar. After all, if I couldn't use my modem, I couldn't check my
email, etc. It turned out to be a problem with my preference file when
converted to the latest version, that was causing the problem. Since
they always started with a new preference file, they couldn't duplicate
the problem that was obvious to me.

Run program in 100% cpu usage

hi all,
does any body know how to set the java program to utilize 100% cpu usage? thanks!

class Empty implements Runnable {
    Empty() {}
    public void run() {
        while(true) {}
    public static void main(String[] arg) {
        new Thread(new Empty()).start();
        new Thread(new Empty()).start();
        new Thread(new Empty()).start();
        new Thread(new Empty()).start();
}Not sure why you would want to do this though?

Copying from USB NTFS device with Dolphin (KDE) causes 100% CPU usage

I am copying +/- 30 GB of Music files (flac) from my external USB HDD which is formatted as NTFS.
I have installed ntfs-3g and am experiencing near 100% CPU usage. What's wrong?
Additional info: I am using KDE and initiated the copying through dolphin. KDE's system monitor only shows CPU usage near 100%, but no processes in the process view could be responsable.
Thanks!

What mount options are used for that ntfs drive?
Edit: There are many similar threads but I couldn't find a solution other than trying out some kernel and cpufrequtils fun.

[10.1.2] Protected Mode causing 100% CPU Usage/Extra Processes on Win XP 32-bit?

Hello,
I'm not 100% sure if the two are related, but I have a client who was seeing 100% CPU usage using Adobe Acrobat Reader X 10.1.2 on Windows XP 32-bit and Firefox 11. The acrord32.exe process would hang around after closing the main window and eventually leading to tons of processes and his CPU at 100% use. I believe disabling Protected Mode may have solved this issue. I didn't see it documented anywhere so I figure I'd post about it here and see if anyone else was seeing this resolved as well.

I noticed 'only' 50 % CPU usage. Not during Reader usage with ~ 20 %, but it started after closing main window.
Two instances of acrord32.exe were created - the moment pdf was opened - of which one was using zero CPU.
After opening another pdf, 2 more processes were created, so 4 in total. Have seen 2 of them using 100 %.
Issue is easily recreated.
This is all in 10.1.3, no fix from Adobe, only THE fix from you: turning of Protected Mode!
After which now only one proces is created, with 1 to 3 pdf documents opened at same time.
This instance is then nicely shutdown after the last pfd is closed.

Itunes takes 100% CPU usage ?
