My T400 with its 100% CPU Usage

hi, i have problem with my T400 approximately for 10 days. Windows xp was installed and it has been heating very much, about 80 degree and higher. i think of virus possibility andI formatted and install Windows 7. However, problem werent solved, it was heating again. And, i install a clean windows xp now but its cpu usage at !00% rate always even if there is nothing works hard. screen shots of tsk manager are at attachment.

Reinstall Lion, Mountain Lion, Mavericks or Yosemite without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, Mavericks, or Yosemite
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

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.

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

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.

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.

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:

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.

SQL query against ConfigMgr DB causing 100% cpu usage on SQL server throughout day

Hi, I am hoping someone here may have an idea of what I can do to resolve this as I am not much of a SQL guy. Here is what I know. Throughout the day, monday-friday, my ConfigMgr SQL server sits at 98-100% processor usage.
Using the following query I have narrowed down the culprit of the high cpu usage throughout the day:
SELECT p.spid, p.status, p.hostname, p.loginame, p.cpu, r.start_time, r.command,
p.program_name, text
FROM sys.dm_exec_requests AS r,
master.dbo.sysprocesses AS p
CROSS APPLY sys.dm_exec_sql_text(p.sql_handle)
WHERE p.status NOT IN ('sleeping', 'background')
AND r.session_id = p.spid
Even though my knowledge of SQL is light, I believe the following output clearly defines the thread responsible for the high cpu usage. This "program_name" is present throughout the day and as long as its there, cpu usage remains at or near 100%:
The text output of the above culprit is as follows (sorry this is long):

If anyone has any experience with this issue or anything similar and might be able to point me in the right direction, any responses would be greatly appreciated. Thanks for reading!

Normally, this summary job every few mins which only summarize last few mins sending history. If the job was not running for long time, the first time, this sproc will summarize a lot more data than normal. So it could fail which will make things worse and
worse over time.
If sending summary data is not a big concern here, you can manually insert a dummy row with most recent time as Summarizationtime, so that, when summary job kicks in next time, it will only summary short interval data.
DrsSendHistory is that the table records every sending on every group. This table is one of the key of replication logic. For your environment, on primary site, it could have up to 24(hrs) * 60 (mins) / 2 (sync interval) * 36(secondary sites) records per
day for Secondary_Site_Replication_Configuration group and 24 * 60 / 5 * 22 records for Secondary Site Data.

Hi Umair,
Thank you for the reply. My plan was to go ahead with your suggestions but what I tried first was to get my VM guy to give the SQL server access to more CPU resources. We had already configured it with what would have seemed to be plenty, as per Microsoft's
sizing requirements, but I figured it couldn't hurt to rule out - he gave the SQL server access to a huge portion of the host processing power and since then CPU usage on the server has NOT been an issue.
It would appear that the large amounts of secondary sites we have just simply put a lot of stress on the SQL server with out of the box replication settings. Since the entire VM host is for System Center only, and our other System Center servers are using
very little resources, this solution has ended up being valid.
Thanks again for everyone's help with this.

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:

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!

[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.

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

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!
