Processing files takes 100% of CPU
When downloading an album, it takes a >5 minutes for each track to get through the "Processing files" stage. iTunes uses 100% of my CPU while processing, also.
I've used iTunes to download albums without problems before-- this seems to be a new problem.
Go to folder "downloads" in iTunes music folder which is the temporary downloads folder for Tunes itself.
If there is any item within (as a leftover from a former download), delete it.

Copy video files then processing files takes to long
first i have to copy the video files which takes about 6 hours sometimes more sometimes less then processing the files takes another 6 hours more sometimes less... am i doing something wrong ro how can i speed this up?
i am copying the files from my mac hd to an external hd... is that the problem?i have copies on one external drive and i am copying them to another drive for for permanent storage and when i copy them over it takes long about 6 hrs... after its finished copying it process the files so that takes about the same time as copying them. I even tried doing it straight from my video camera to my mac and after that it has to process the files...i dont understand why it even does this. this never happened with imovie 6 hd or even final cut express it only does this with imovie 8... to me it does not make any sense. i thought things would be faster in imovie 8 but it doesnt seem to be...

Processing File takes too long
I have downloaded a number of albums on iTunes before and in recent times, the processing file is extremely slow. It takes about 95 seconds to process a 14MB file and considering that most of the music I download is around this size it is very frustrating.
My internet speed is normally 54Mbs with a good connection and I have checked that I don't have the V CAST from Verizon so there is no conflict there. I currently have 7GB of music in my library.
Does anyone have any suggestions on what I can do?I think when it sees that declaration, it tries to actually download the DTD so it can validate the document against it.
So the time delay is the network connection.
There's a simple way to turn this off but I forget what it is.
There are also klugy ways to turn it off but I won't say how so as to not poison the well. -
Installdb process takes 100% of CPU
Hello, I've just installed OS X 10.5 Leopard as Tiger upgrade. Everything work really slow, comparing to Tiger. The thing I've noticed — process named installdb takes all the rest of cpu power. I mean, cpu usage is always about 100% because of this. I've tried to quit installdb process, but it relaunched again. What is this and is there any way to kill it?
PS I'm currently running Safari, Finder and Activity monitor only.

Hi,
when I am using iWeb, the mds process takes de 100% of the CPU. If I close iWeb, it stops. It also happens when I a watch a video on Aperture 3.
It started after 10.6.3.
What can I do?
Thanks in advanced
Message was edited by: plcnThe mds process is Spotlight indexing your hard drive. As you create new files/projects, it indexes them for fast searching.
It is extremely processor hoggy and personally I turn off indexing on my drives because of this issue, and I never use Spotlight to search for anything anyhow. I know where I put/keep my stuff.
To turn off indexing, go to *System Preferences* > Spotlight > Privacy and add your hard drive to the list.
The mds process will bother you no more. -
I have an itunes library of 4000+ albums and 70k+ songs. Worked great until itunes 11 today. Now, when ever I go to the search field and type 1 character, I go to 100% CPU busy and all the other characters are lost. "itunes not responding" for a couple of minutes.
Also happens when I am importing a CD from physical media, and I switch to music and try and find another album. Gui becomes unresponsive and activity monitor ends up reporting "Itunes (not responding)".
How go I go back to the working itunes?Thanks. That was it I don't know why it got changed during the upgrade to iTunes 11.
However, it still takes 5-10 seconds for this menu to appear, with the cpu at 100% one core. Seems like iTunes should support multi-threaded/multi-core processing, especially for the GUI. -
10.6.8 another problem dock takes 100% of cpu
I discovered 10.6.8 broke the printing on my Epson RX650 multifunction printer. There are work arounds to deal with that I understand.
Now I find in Activity Monitor that the dock is consuming 100% of one CPU. I can force it to quit, it comes back after a short while at around 14% CPU then shoots up to 100% again. In the floating CPU window of Activity Monitor I see one core is fully utilised. I get Dock to quit and it will come back and hog another core.
Any suggestions?Problem sorted. Saw another discussion that found Parallels as the culprit. Also saw that an update is available from Parallels that fixes the bug.

Airport process consuming 90-100% of cpu time
I have first gen Macbook Pro, 2Ghz. Just in the last day or so, I've noticed that the "airport" process is pretty well using up one of my CPU cores. I can kill it and I don't notice any problems.
I have read the article explaining that third party VPN software can cause this, but I have no such software installed.
edit: I've noticed that it does this when first booted. If I use airport status in the menu bar to turn off the airport card and then turn it back on, the cpu usage goes back down. Anyone know what might cause this?

DPS 6.3 takes 100% of CPU time
I've 2 couple of DPS 6.3 proxy servers running upstream 2 couple of DS 6.3 on RHAS 4U6, JRE 1.5.0_16-b02
located on 2 different sites.(6.3_KS_6661375_6670752_6654625_6513526_6653253_663073_6723858 B2008.0717.2043)
I notice about once a week to every 2 weeks that a proxy server on each site starts to send
to me warning messages about an LDAP data source not available on the remote site.
The proactive monitor thread logs messages such as "exceeded maximum allowed timeout of 10000 ms" .
The problem is that when it occurs, the proxy starts to take all the available CPU time so that there's
no other solution than restarting it .
Known problem ?The problem occured today, I had about 35 threads running among which the 5 below were taking all the CPU time,
the others being under 2% CPU :

IChatAgent takes more than 100% of CPU
The iChatAgent takes more than 100% of CPU. It works normally for 10-15min with little CPU usage but then takes 100% of CPU and stays like that until I quit/kill the process. I tried waiting for hours to see it might go down is usage, but no, and the cpu fan remains on continuously.
I simply use it for text based chatting, and have disabled audio, video,microphone etc, and still this behavior that I can't use it for more than 15min.
Here is the iChat version: Version 5.0.3 (745)
Macbook Pro/10.6.4/Intel Core i7
I have tried removing ~/Library/preferences/com.apple.iChatAgent.plist as suggested elsewhere, and that hasn't helped either.Thanks again Ralph.
No, I do not have any add-ons, just out-of-the-box ichat without any audio, video in use.
At this stage unfortunately, I can't continue using iChat as it hogs up the CPU in less than 15min. And that I do not experience any problem with other chat-clients such as AIM or jabber, so switching over to those until there is a resolution.

Java process take 100% cpu
Hello,
I have a webapp running on Tomcat 5.0.28/RHEL 3.0. After some time (approximatively 1 hour), a java process take 100% cpu load and never stop, but the application do nothing.
Some detail on my configuration :
Distribution : Redhat Enterprise Linux 3.0 (updated)
Kernel 2.4.21-37.0.1.ELsmp
Glibc 2.3.2-95.37
JVM : JRockit 1.4.2.08 (the last one)
Tomcat : 5.0.28
Server : 2*Xeon 3GHz HT, 2Go RAM
JVM param : -Xmx:256m -Xms:256m
Thanks for your answers ...Try taking thread dump (send a SIGQUIT to JRockit using "kill"). If you
get a thread dump, the VM is alive, and it's probably your java program
that's broken. In that case, make a JRA recording to see what's happening:
http://e-docs.bea.com/jrockit/docs142/usingJRA/jra.html
The methods pane is probably what you're looking for.
If you don't get any thread dump when sending a SIGQUIT to JRockit,
come back here.
Regards //Johan

in addition you might want to trace the session to find out what it is waiting for. In 10g you can use the DBMS_MONITOR package to enable the tracing, and then use the "tkprof" utility as outlined in the article to get the trace file generated analyzed.
You can also use the V$SESSION view (BLOCKING_SESSION_STATUS, BLOCKING_SESSION, BLOCKING_INSTANCE) to find out if the session is blocked for any reason, although it shouldn't consume CPU in that case.

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.

Labview Loop Takes 100% cpu
Hello,
I'm wondering the best way to send a serial command when a button is pressed. Right now I have a while loop that checks if the button is pressed each time. If is is, it sends the serial command and adds the response to a text box via a shift register. If not, the original text box info is passed to the shift register. However, this loop takes 100% cpu (ok, only one core at 100% so technically %50), and I think its because the text box is getting overwriten every cycle. However, I'm not sure how else to do it. Attached is a print screen, let me know if you would like the file.
Thanks,
Eric
Solved!

What is your veriosn of Oracle? what is the OS? which oracle process is consuming 100% CPU? how did u find out it is conuming?
and you have mentiond query is tuned one... it does your query is taking time to execute?
