Persistent Active Requests causing high CPU usage and load average

Hi, we've deployed a JSP application on standalone OC4J talking to Oracle DB. The whole thing runs on Sun Solaris. On some occasions (still investigating what causes this), the number of active requests rises (as seen from EM console) and never drops down. The weird thing is, the load average numbers are proportional to the number of persistent active request. If there are 3 active requests, load avg will be [3.x 3.x 3.x], and whenever persistent active request exist, CPU usage will shoot up to over 90% (usually between 95% - 100%). When the system is running normally, CPU usage is usually less than 20%. Is it possible to track down this problem and how? Many thanks.

Welcome to Apple Discussions!!
The icons on the right of the menu bar … show a beachball when I put the cursor over themWell, if this was your only problem I would put it down to a corrupt preference or cache file. Nevertheless, it is worth seeing how much this helps.
The file you need to trash is 'systemuiserver.plist'. But there are potentially two of them, plus it is best to delete your caches as well, so ...
In "/Users/<yourname>/Library/Caches", delete everything
In "/Users/<yourname>/Library/Preferences", delete com.apple.systemuiserver.plist
In "/Users/<yourname>/Library/Preferences/ByHost", delete com.apple.systemuiserver.xxx.plist where 'xxx' is a 12 digit (hexadecimal) numeric string.
See if this improves the situation, and post back with any remaining oddities.

IcedTea High CPU usage and multiple jobs created

High CPU usage and multiple jobs created while streaming data via a java applet from a secure/certified website. CPU usage is normal for a few minutes then suddenly jobs multiply and CPU usage climbs on one of the jobs.
Jobs with the following command begin to multiply in my job queue with one job showing CPU usage at 368% and staying resident in memory (yeah, a long one):
/usr/lib/jvm/java-7-openjdk/jre/bin/java -Xbootclasspath/a:/usr/share/icedtea-web/netx.jar:/usr/share/icedtea-web/plugin.jar:/usr/share/java/js.jar: -classpath /usr/lib/jvm/java-7-openjdk/jre/lib/rt.jar sun.applet.PluginMain /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-plugin-to-appletviewer /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-appletviewer-to-plugin /run/user/1000/icedteaplugin-tbattist-SZ3xKO/7160-icedteanp-plugin-debug-to-appletviewer
I have the following java packages installed on my system:

I also get the following message in my system log when starting to stream:

Anybody having this issue or clue on what to do? I am wondering if recent changes to openssl (heartbleed) might have java change ramifications? Should I submit bug to Icedtea?

...further research and learning.
Here is a good tutorial on Java. Evidently, what I called "jobs" is referred to as processes and threads in this tutorial. The tutorial states that multithreaded execution is an essential feature of the Java platform which explains the avalanche of threads I observe. However, I am still stumped at what causes the avalanche of threads and excessive CPU consumption for such a mediocre task. Also the system log says that IcedTea has an error stating "Application title was not found in manifest. Check with application vendor". I interpret this to mean that IcedTea does not recognized some application. What application? .....the applet?

Microsoft Office 2004 -- extremely high cpu usage and virtual ram

hi,
when i use office it causes a very high cpu usage even when its in idle mode.
i am unable to work with it, because its extremely slow.
does anyone have same experiences?
thanks for your help!
mbp 2.0 1,5gb ram 80gb hdd Mac OS X (10.4.7)

I am able to work OK with office, I'm using the 'old version' Microsoft Office v.X, not much details in the About Box, just listed as MSoft Word/Excel/etc for Mac service release 1.
I get the occasional crash, and I have seen Word in particular use 90% of a single core and amazingly large virtual memory usage, gigabytes sometimes, but eventually the document gets printed.
It shows how useful the dual core (or quad) cpu approach is!
One cpu for Word to print, and one cpu to run the rest of my applications/life!
I still use this old office rather than re-booting into Window§ for whatever is the latest version of office.
Doing some playing with a similar one page document in Office v.X and Pages 2.01, I get Word using about 25% of a core , Pages using 5%, - whilst editing; Intel native Pages has 20% of a core and 80MB ram 480 virtual whilst printing, Word has about 100% of a core and 65MB ram 650 virtual whilst printing, but it is a powerPC code so Rosetta is in there somewhere.
check Activity Monitor or other apps/widgets for some parasitic processes? have fun!

Mixer window can cause high CPU usage, crashes

This is probably one of the weirdest bugs I've seen for a while. Here are the steps that I reproduce it for me, maybe someone will want to try this out and see if they get the same.
1) Open an Empty Project template.
2) Create 16 instrument tracks when it gives you the dialog. (even 1 will be enough, but the effect is clearer the more tracks you create)
3) Open the mixer. Either in a window or in the pane.
4) Now create a "multi-timbral" instrument track with the plus button (use the checkbox there).
5) Select the 16th track, and now select one of the arrange tracks of the multi-timbral instrument.
6) Open up Activity Monitor from your Utilities folder in Finder and see how much Logic is taking up CPU. It should be significantly higher than the idle state. On my MBP it'll be around 80%.
This is not a problem in itself, because when reproducing it like this the high CPU usage goes away when you select another track and won't return if you select the multi-timbral instrument again.
However, I have sessions where this will continue happening with a multi-timbral instrument all the time. Not only that, I've had Logic crash when this starts happening. And this whole thing will slow down the UI considerably when it's active.
The workaround that seems to work for me is simply not keeping the mixer window/pane open.

This is one of the issue which has already been raised to Microsoft and hopefully a public build will be available soon in next cumulative update pack .
There are variety of reason for this starting for password mismatch or password not given , SFTP adapter unable to connect and so on .
There is good post here in below link for this issue
http://thoughtsofmarcus.blogspot.co.uk/2013/06/leaving-password-blank-in-biztalk-2013.html
Another greate artcicle is by Nino which states these issues .SFTP adapter is protocol sensitive and some configuration by server side, can cause a lot of crazy situations

Adobe stuffs cause high CPU usage

I just download Creative Cloud a few days ago for Primiere CC and since then there is always something from it that causes ~50% CPU usage. I tried to end the process by Task Manager and something else just replace the previous one's place. Sometimes it's CEP Service Manager, sometimes it's Core Sync, CEF Helper, etc. and it's driving me nut! I mean like right now Firefox only takes about 20% while those things just sky rocket the CPU usage. What should I do? How do I stop this?

Since I installed CC, my laptop has been running very hot too.

High CPU Usage and Temperature

I've recently purchased a MacBook with the latest updates, including the firmware for the random shutdowns but lately when I boot the MacBook up, the fans kick on and it reads 83 degrees Celsius with about 65% CPU Usage and I don't have anything running except what came on the MacBook in itself, any suggestions?? Apple told me to take it in to have it looked at but I was wondering if there is anything I can fix perhaps?? Thank you

Sometimes when I connect an external drive which I have made drastic file changes to, there are two process that eat up a lot of cpu power and get the macbook really hot for awhile, those two processed are related to the way spotlight tries to re-index the external drive or the internal hd itself if I had made drastic changes to it too.
Could it be that?
You can see them show up in Activity Monitor, they are mdimport and another one starting with md(something) too.
Hope that helps (if that's the issue)
Best,
Pedro

Wake-On-Lan (WOL) after sleep causes high CPU usage

Hi,
I noticed a problem with constant high CPU usage on one of my cores.
As much as 60% was used.
The problem occures after I put the system to "sleep" (S3 state) and perform a WOL with a "magic packet".
I discovered that ACPI.sys+0x1af44 thread was responsible (using sysinternals ProcessExplorer) under the System process.
If i perform WOL while the machine was shut down everything works perfectly.
My NIC is "Realtek PCIe GBE Family Controller" and I'm using the latest drivers.
I discovered that if I disabled the option in Power Management for the device: "Allow this device to wake the computer", the CPU usage immediately went to normal (without restarting). But enabling it back the high CPU usage resumes. Performing
another sleep and awaking the system with power button "resets" the CPU usage issue for "good". Until i WOL from sleep again ofcourse..
I contacted the motherboard manufacturer of the problem but so far no real answer.
I'm saddened because I need the WOL feature.
I'm hoping somebody who has more insight in the behaviour of ACPI on W7 can answer my questions.

What Causes High CPU Usage Even When PC is Idle

How can I fixed the high cpu usage on my pc?

I think most people have been seeing the problems in any of the 2.6.35 kernels, so 2.6.34.3 would be my recommendation
+1
And put kernel26 in IgnorePkg.

Rim.desktop.exe high cpu usage and internet activity

What the heck is going on with desktop 6 software? Rim.Desktop.exe is running 10-20% cpu utilization and my router lights are blinking like crazy. It won't shut down right away while this is going on either. I have to force the shutdown to close the app and stop the internet activity. This goes on when my phone is connected or not. Storm 9530.

Thanks for the quick reply.
If you do not have that 3rd party add-on running, do you notice a difference in the cpu usage? or network connectivity?
Also did you experience any of these problems with running with DTM 5.0.1
The only network connection that Desktop Manager uses is to register the PIN number and to check for updates and down the new updates. But it does not continue constantly.
I would see if you can use BlackBerry Desktop Software without the 3rd party add-on unless you tried before, to see if it's a third party add-on causing the issue or Desktop Manager.
I look forward to your results.

Flash causing abnormally high CPU usage and overheating when browsing internet

Hello,
Flash Player (Safari Internet plug-in) spikes to 110-120% of my CPU usage while browsing the internet. This also causes my computer to overheat. (This also occurs when using Firefox)
I am running OSX 10.8.4 and I am using Adobe Flash Player 11.8.800.94
I have tried uninstalling through the Adobe uninstaller and resetting Safari and my computer.
I contacted apple care and they said it was a problem with Adobe and I needed to contact you guys.
Thank you for your help.

The link you posted is fine. its only around 9%

Applet causes high CPU usage

Hallo,
I have a strange problem with my applet. It displays medical images. After loading Image the CPU usage of java jiumps to 100% on single core processors and to 50% on 2 core processors, and stays high, without any interaction of user. I've used Java VisualVM to profile the applet and it says that: javax.swing.SystemEventQueueUtilities$ComponentWorkRequest.run() 94.76343 787851 ms (94,8%) 58823 times invoked is
I'm not sure this is the cause of the problem. I don't use any loops while noone is interacting with the applet. Has anyone idea or suggestion what's going wrong?
This CPU load is independent of browser and operating system. I've profiled it on firefox.
with regards
Rafal Ziolkowski

Good job figuring it out.
Rule of thumb to prevent future problems: the paintComponent is used for painting and should do nothing else - setBorder() is a state change and thus does not belong in the paintComponent() method. You can all relate it back to a general programming rule of thumb: a function or method should perform only one task.

High CPU Usage and Low battery life

Hi to all, I have this problems, my cpu is always over 40% an battery life is short. Before I installed 10.6.2 my battery duration was 4 hours, now is 2 hours. I tryed SMC reset, but the problem is on the CPU usage.
This are Monitor Utility screen print.

Those permissions messages may be ignored. They are normal.
Because everything is OK in safe mode you need to track down what isn't active in safe mode that may be causing the problem you are having. Of importance are:
1. Incompatible third-party extensions (drivers) such as may be used for third-party peripherals.
2. Incompatible items located in the /Library/StartupItems/ folder or /Home/Library/LaunchAgents/ folder.
3. Bad fonts located in the /Home/Library/Fonts/ or /Library/Fonts/ folders.
4. Incompatible item in your Accounts' Login Items section.
5. Corrupted caches located in the /Library/Caches/ and /Home/Library/Caches/ folders.
To test the corrupted cache possibility simply remove the above mentioned cache folders to the Trash (but do not delete) then restart the computer normally. If the problem is resolved then you can empty the Trash.

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

High cpu usage and game lag problem

i have a hp 15 d103 tx
windows 8.1 64 bit
inel i5 4200m 2.5ghz
anti virus installed avast fee antivirus
im using nvidia 820m geforce 344.75 version driver
ram installed 8gb
im experiencing huge amount lag in games and software (autocad)
whenever i run a game (for eg batman origins) it run smooth till 2 or 3 minutes after it lag horrribly
for sake first im getting 45 frames per second then suddenly frame drop to 13 or even to 10
i have to press alt + tab to check task manger it show cpu usage 30%
after that when again i press alt tab to back to game it runs fine for 20 seconds and again lag
i dont what the problem high cpu uasge
system idle process sometime shows around 82%
with 8gb of ram still expericing lag
this problem is with all game that i have played and software like photoshop and auto cad
my cousin own hp 15 r007tx and having same gpu nvidia 820m game runs for on his laptop without a lag
is it window 8 problem or something else??

wow finally got the solution by updating bios
just updated the bios from 2.7 to 2.8
no lag now
i guess different cpu load gpu switching on off was problem
but now everything is running good

High CPU usage and program slowing down

Hi. I have helped write a program in AS3 that uses classes. We have 2 frames in our movieclip that consists of an ant moving. We have a class of ants and can create 15 instances of them and the program runs fine with the ants walking around looking for food and going back to a corner that is their nest and going back out again. The ants also respond to mouse movement if the mouse pointer is near an ant.
If we create more than 15 ants, then the program starts to slow down. If we have 30 ants on the screen, then there is noticable stuttering of the ant movement. The CPU usage on a P4 2.5Ghz Pentium is around 50%.
Is this normal? or is something wrong?
I would have thought we would be able to scale up the number of ants easily.
Thanks
Trev.

Hi kglad.
Thanks for the reply.
I assume enabling cacheAsBitmap is set in the ant class Constructor, as we have tried that and it has helped, see below. We can now create 30 ants with very slight stuttering.
We have an ant class as below.
public class TAnt extends MovieClip { // lots of code here }
ant Constructor as below.
public function TAnt(newX: Number, newY: Number, sW: Number, sH: Number, rCyc: Number) {
            this.cacheAsBitmap = true;
           // more code here }
// We have implemented a Finite State Machine for the ant behaviour.
regarding the ants using a loop and using a controller class, I am not sure what you mean.
We are creating instances of the ants in the Ants.fla file which is in the Action file and add each new ant to an array. See below.
for (var a = 0; a < nAnts; a++) {
    var newAntX = Math.random() * screenWidth;        // randomly generate ant location
    var newAntY = Math.random() * screenHeight;
    var rCyc = Math.random() * 800;
    var ant = new TAnt(newAntX, newAntY, screenWidth, screenHeight, rCyc);            // create ant
    addChild(ant);                                                   // add ant so visible on screen
    ants.push(ant);                                                 // add ant to array
So we use an array for looping through the ants in the Ants.fla Action file.
Is this the way you mean?
Thanks
Trev.
