Safari causes my computer to run at 100% CPU Usage!

For the past few days Safari has been causing my CPU to run at high rates. This basically causes me not to be able to much while Safari drags and loads pages. I need a solution to this. I tried resetting Safari but that didn't work. Please help. Thank You.

My PC runs at high rates too. And I too like to use iTunes at the same time I use Safari.
And there's no quick solution to this...at least not yet. But here are few tips and tricks that you can apply to get this thing half solved.
1. First of all, if you don't intended to watch images while browsing, You can turn it off...Simply by going to 'Edit> Preferences> Apperance (Tab)' and from there deselect ' Display images when the page opens'
2. Secondly, Don't open too much tabs if it's not needed.
3. Thirdly, if you're using Safari for a few hours. Just try to close the whole window time to time. And after reopening get back to the last session (View) by selecting History> Reopen all windows from last session'
This will probably help you. Btw, these tricks are exclusives from me. Happy Surfing buddy!

In Oracle 10g,nmupm.exe runs at 100% CPU usages

Hi There this is Bal Mukund Sharma from Computer Associates,HYD.I have recently installed Oracle 10g on windows 2000 server with 1 GB RAM,i have observed that nmpsupm.exe which is under the bin directory under c:\oracle\product\10.1.0\Db_1\nmupm.exe.is consuming all CPU resources.
when i set all Oracle services to manual and restarted the machine then it shows normal CPU usages. Can you please suggest something regarding this.
Regards
Mukund.

This is a known issue, see here

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.

Crystalras.exe consuming 100% CPU usage

Hi everyone,
When we try to open an instance of one of our Crystal reports from InfoView, the crystalras.exe process runs at 100% CPU usage and the report never shows up. After a few minutes, we get the following message:
The request timed out because there has been no reply from the server for 600,000 milliseconds.
Does anyone know where the problem could come from? Could this be because the report is retrieving too much data?
Thanks in advance for any help.

Dear Both,
I traced the RAS server as suggested by Tim and obtained a log that - I have to admit - is quite difficult for me to understand. Could I send it to one of you for examination? Thanks in advance.
Ted, please find below my answers to your questions:
Just to close out possible data source issues, are the reports going against Business Views or Universes?
The report is based on Business Views.
Do you have Processing Extensions specified for the reports?
Sorry but what are Processing Extensions?
Also, when you checked in the Crystal Reports Designer, was it Designer installed on the same machine where the page server and RAS server is running?
Yes, it is installed on the same machine.
Also, since it affects both Page Server and RAS, it may require CRPE traces to get to the bottom of this (CRPE - 'creepy' - is the CR engine used by both the Page and RAS server).
I will certainly open a case with SAP to have them help me on that.
Thank you both for your help. It is very appreciated.

Flash Player Causing Whole Computer to Run Slowly

Everytime I go on a page that uses flash content (which is
quite often) it causes my computer to run really slowly and I am
constantly having to restart it. I have tried uninstalling flash
player and re-installing it, re-installing internet explorer, and
updating my drivers and nothing is working. I am at a loss as to
what to do next. I will welcome any suggestions. I am running
Windows XP with IE7. I am taking online classes that use flash
content in some of their material, so it is very important that I
get this problem fixed.

Hello!
some virus attacks through flash player. As I've got an old
system and W98 i've only a problem with my graphic drivers.
Microsoft gives an alert that they detect such attacks during

I'm really sorry for you, adobe refers to uses conditions and
disclame any interest in that sort of problem. If I don't find a
solution for me,
1/i'll reinstall my system
2/i'll never use flash player in the future except if they

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!

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.

if you still do not know how to Fix CPU Usage 100%?
I suggest you try targeted software - registry cleaner to fix cpu usage 100%
Because there are many cases causing high cpu utilization.
1. If you do a lot of web surfing and are concerned about spyware, adware infecting your machine, they will cause system crashes and CPU utilization reaches 100 percent. Some good registry cleaner has the function of spyware & adware removal.
2. You install many beta version of the software, Drivers are not certified, which resulted in many errors, you get high cpu usage.
3.100% CPU Usage while you use Internet Explorer
4. many unneed Startup Program.
5.Others PC Errors. - DLL errors, runtime errors, Windows-Installer Errors, Windows Startup Errors,paths Broken DLLs, OCX, and ActiveX Components all will cause 100% cpu usage. Your PC will run very slowly.

Recently FireFox often has been causing 100% CPU usage and locks up until it finishes the process (various ones). Clearing cookies/cache didn't help. Any ideas?

Windows 2000 SP4, 1g RAM, Firefox 9.0.1
We keep IE6 and Firefox open simultaneously for 2 different mail accounts. Firefox was always much faster even with 3 or 4 tabs open, but for the past couple of weeks when trying to update a screen the CPU suddenly goes to 100% usage and of course nothing will move until the particular process is finished. Closing one or more tabs does not help. If I close Firefox completely with Task Manager CPU usage goes back down to nil. After restarting Firefox CPU usage may or may not go back up depending upon whether it tries to continue the previous task that was locking it up.
It did not do this with Firefox 3.6 but then again it didn't happen immediately after updating to 9.0.1 either.

100% CPU usage occurred most often toward the end of the working day when busy trying to print on-line postage. We don't have any memory-consuming plugins but according to the knowledge base articles Firefox memory usage can gradually increase during the day even if you do nothing. It seems that may be the problem so we close and restart Firefox more often now as that usually fixes the problem. However, if we get stuck on a particular website update that causes the CPU to to go 100%, we can always start Firefox without previous tabs so the update will stop, or simply use a different browser until we have time to let the computer play games with itself.
So our workaround of restarting Firefox turns out to be the final solution (until we find something better - will post it if we do). Vic

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)

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:

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.

Shockwave Flash 11.6.602.168 100% CPU usage

Hi,
Our computer has 100% CPU usage every time we get in websites that utilize Flash, or watch youtube.
Browser: FF 19.0
Flash 11.6.602.168
Computer: HP Pentium 4, 2.8 GHz, 3G memory, up-to-date BIOS and other drivers.
Graphic card: EVGA GeFprce 6200
Windows 7 32 bits
This window is freshly installed, has AVG on. We do not have many software's installed, except MS Office. All fans and CPU are clean. The computer runs fairly fast: we tried opening multiple FF tabs simultaneously, plus Excel, Word, Solitaire etc. without any problems. However, whenever we get into websites with Flash, the CPU uasage goes to 100% and stays there. Memory usage has always been stable, around 30%. We have tried the following steps, but it hasn't gotten better:
- Turned off all applications, opened only one tab with that website.
- Updated all drivers and applications: FF, Flash, Graphic card etc.
- Turned ON and OFF hardware acceleration for both Flash and FF, also tried to turn one On, the other OFF, and vise versa.
- Disabled all add-on's, extensions and Plug-in's, except Flash.
- Uninstalled and reinstall FF and Flash; restarted several times.
- Temporarily turned OFF protected mode.
- Uninstalled FF, Flash, then installed IE 9, then Flash for IE: didn't work.
- Uninstalled IE 9, Flash, then installed IE10 then reinstalled Flash for IE: also didn't work.
- We do not keep browsing history.
Examples of websites that we have had problems with: pbskids.org, barbie.com, and other school websites for kids to do homework or watch youtube.
While in many websites such as CNN.com, yahoo.com, when we opened it, the CPU usage did spike, but came back to 1-5% within 5 seconds.
This computer is for our kids. Do we really need to buy an i5 or i7 computer so the kids can play and do homework? Or is there any other way that we can do?
Thank you

Moving to the Using Flash Player forum, as this isn't specific to the Beta.
In the Youtube video, if you right-click and choose Show Video Info, it will show you whether you're using Hardware Acceleration for both Video Rendering and Video Decoding.
If you're seeing Software Rendering and/or Software Decoding and you're watching a high-def video, it's going to use a ton of CPU.
Do you see similar behavior in other browsers? (Chrome, IE) The Flash Player distributions are actually quite different for each browser. It would be an interesting data point.

How to control timing without 100% CPU usage

I wanted fine control over timing (in windows XP), but ran into two problems.
Problem 1: If you use the Swing timer, or Thread.sleep, the resolution is limited to 10 or 11 milliseconds. There is a Thread.sleep(millis, nanos) function, but I tested it and it still has 11ms resolution in WinXP.
Problem 2: If you use jbanes's GAGE timer, CPU utilization will always be 100%.
Solution: Use a hybrid technique. I would love to have nanosecond resolution AND low CPU utilization at any speed (and if you have any suggestions, please post them) but for now:
class /*name*/ extends Thread{
public void run(){
          setDelay(delaySettings[speed]); //Set "delay" to the desired delay in nanoseconds
          long nanos;
          while(true){
               if(running){ //"running" is a boolean that can pause or unpause the game
                    nanos=System.nanoTime()+delay;
                    tick(); //Do the game logic and graphics for one frame
                    if(delay>11000000){ //If the system timer can handle it
                         try{sleep(delay/1000000);} //delay/1000000 gives millis
                         catch(Exception e){System.out.println("Caught sleep exception: "+e);}
                    }else{ //use a nanotimer (cpu-expensive)
                         while(System.nanoTime()<nanos){}
               }else{ //it is paused, so wait a bit
                    try{sleep(50);}
                    catch(Exception e){System.out.println("Caught sleep exception: "+e);}
//The rest of your code
}If your desired delay is greater than the system timer resolution (here, I have it set at 11,000,000 nanoseconds, or 11ms) then you can use the Thread.sleep(milliseconds) call, which will have approximately 0% CPU utilization until the thread wakes up. Theoretically, you could use this time for another thread, but at the very minimum, your computer should use less power / generate less heat. If your desired resolution is smaller than 11,000,000 nanoseconds, it goes into a loop that checks nanoTime()... which gives you 100% CPU usage, but is very accurate. This works pretty well if you want to control the framerate dynamically (I use the "-"/"=" buttons to adjust speed) and it handles "pause" events, though I'm sure there are better ways to do that.
Note: The timing granularity above 11ms for this technique is probably 11ms, though the code could be modified to provide nanosecond granularity at any speed.
Note 2: I found this to run 3% faster than when I used the GAGE timer.

Pause the game when u alt-tab away ^_^
Thats what most native fullscreen games do (the
non-networked kind atleast)Good idea, but the crux of the issue is really the underlying scheduler which allows
the thread to race.
How to "Eliminate" 100% CPU usage.
Tony's Law of the exec constant. <<<<"Any thread or process running on a non-preemptive operating system MUST NOT use blocking
IO, and MUST preempt itself at leat 20MS per iteration."
The reason it is called a constant is because it is the minimum time needed to ensure
the underlying operating system gets enough CPU cycles to function correctly.
Every milliseconds below this increases exponentially the chance of locking up or
crashing despite the speed of your system.
Most people who program do not realize the the implications of running under defective schedulers
such as the one provided with MS windows where, for example, you can block on a socket, and
hang your whole system.
>>> Do NOT use Thread.sleep() <<< but instead use Object.wait();
Do not use blockng IO. If you have to use java.io, use available() to make such you ONLY
read the exact amount of bytes you need without blocking and make sure to prempt
yourself at least 20MS per iteration.
ie:
InputStream inputStream;
while(working)
Object waitObject = new Object();
int readCount = 0;
int availableBytes = 0;
int totalBytes = 10;
   while(readCount < totalBytes)
      if((availableBytes = inputStream.available())!=0)
          read() (the # of Bytes available)
      else
          synchronized(waitObject)
               waitObject.wait(200);        // 5X per second poll
                waitObject.notifyAll();
Using wait() removes the current thread from being scheduled; Thread.sleep()
leaves the Thread on the schedule list. wait() releases all monitors allow other
threads to have them; THread.sleep() does not.
The 100% CPU issue is especially bad under NT BTW.
If you do this not only will your CPU usage go to negligible, but you
will never again lock your system because of it.
Good Luck!
