Instense hd activity and 100%cpu make my system completely unsable
hi.
it happenned the first time with some app (i don't know which one) using the hard disk quite intensively.
and then i couldn't even move my mouse. well i move it but 10 seconds later the pointer move on the screen. and i coudn't do anything under X. even type something.
i manage to go to a console via CTRL-ALT-F1. but couldn't login because login give me a time-out ! and then i finally rebooted so i could get back my system and use it.
then,later, i decided to run dd if=/dev/urandom of=/somepartition bs=1024 before setting up a crypted partition. and it happened again !
the hard-disk activity and the 100% CPU usage . and i couldn't do again anything except reboot !!
when i run the same dd command on my Arch 32 bits. it does give 100% CPU usage too but i can still use X without problem. even without any slow down.
so the 32bits system is an old Athlon XP 1800+ with an IDE disk.
and the Arch64 is a brand new Athlon 64 X2 4400+ with a SATA drive and a nforce chipset MCP61.
so what is the cause of that ? clearly the cpu is so used that nothing could work. but on the 32bits system too. and it still works. so ?
is the configuration of the kernel of arch64 different from arch32 ?
i am thinking at compiling my own kernel with PREEMT configured or even compiled an rt kernel. but why is this needed whereas on the 32bit arch all is fine ???
may be that's bs=1024 the problem and what that caused the slowdown ?
or may be i mistyped /dev/urandom and used /dev/random ?
i am using now :
schedtool -B -e dd if=/dev/urandom of=/somepartition
and it works nice. no more than 50% CPu usage. and no slowdown...
the schedtool -B is to be sure there will be no freeze and that dd will not take all the cpu power...

OHJ4.1.16 Repainting Problems and 100%CPU on java 1.4
Hi
We are considering using OHJ4.1.16 as our application help, I have it working such that when the help is invoked either from the toolbar or the menu OHJ is displayed, but there are major repainting problems when the OHJ window is closed by clicking on the X button and then the help is invoked again from the toolbar or the menu item.
Please note that the first time it displays and paints fine only when the OHJ frame is closed and invoked again the problem occurs
The problems encountered are repainting(really whacky), 100% CPU utilization
Please have a look at the code below and tell me if i am not doing it right, Also is there anyway i can trap events on the OHJ frame so that i can dispose it everytime the window is closed by the user??
The following code is executed when the help is invoked
public void startHelp()
helpObject.showNavigatorWindow();
helpObject.setVisible(true);
public static void launchApplication()
String helpset1 = "/resources/help/Test.hs";
Vector booksVector = new Vector();
booksVector.add(helpset1);
if(m_instance == null)
m_instance = new ApplicationHelp(booksVector);
else
m_instance.startHelp();
we are using java 1.4, the above problem makes OHJ unusable!!Hi, John. We're trying to reproduce your problem. If you run any of the OHJ 4.1.16 demos in the bin directory of the installation, do you run into the 100% CPU utilization problem? If so, how? The cshDemo.bat file creates a dummy application that has an OHJ deployment, so please test that one in particular.
Thanks,

High Fan Noise and 100% CPU usage by Dock
My MacBook Pro 3.06 GHz Intel Core 2 Duo running 10.6.8 just started making a constant fan noise. When I checked the Activity Monitor, it shows my Doc CPU usage as 100%, and my Percent User Usage is about 52% System 2.5% and % Idle is 47%. These numbers are when there is nothing running except Activity Monitor. When I log out and log in as another user, the high fan noise stops, and the CPU usage of the Doc is <1%. I have tried restarting my computer, Rebuilt my Permissions, Emptied the Trash, and Reset the SMC (I think I did it correctly for the MBPro, but the Power Light did not change, and nothing seemed to be any different on my computer.) I think I recently did a recent Apple Update, but I don't know how long ago that was. But it was sometime in the past few days. Does anyone have any idea about what could be going on?
Thanks,

Safari hangs, beach ball and 100% CPU confusion
I'm struggling!
Safri 5.1 on Lion 10.7.3 and on both my Mackbook Air and iMac after the recent updates something is stopping Safar from loading. It just hangs, beachball kicks in and the CPU shoots upto around 100% with a "web process".
I've turned off and deleted all extensions, Flash, Flip4Mac, Perian, Ad Block, 1Password etc and restarted and the problem remains on both computers.
I'm stuck. Any help would be appreciated.
ThanksPlease read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are several lines of text in monospaced type, which are UNIX shell commands. They’re harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of running these commands, search this site for other discussions in which they’ve been used without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
To begin, launch the Terminal application; e.g., by entering the first few letters of its name in a Spotlight search. A text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” (without the quotes) and press return. You should then get a new line ending in a dollar sign.
Step 1
Copy or drag -- do not type -- the line below into the Terminal window, then press return:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(x|postfix|ntp|cups)/{print $3}'
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item'
Remember, steps 1-5 are all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password. Also remember to post the output.
You can then quit Terminal. -
Load testing and 100% CPU Utilization - Multiple JVMs?
Hi,
Problem:
While stress testing the application with 20 simultaneous users, unix is 100% utilized and there is degradation in response times.
One component of the application is invoking a unix script which is executing a java program after setting CLASSPATH, PATH etc. I guess thus each execution will be invoking a jvm. At the end of the program it will do a System.Exit(). This java program generates around 15-60 barcode images. It takes 2 secs normally.
When, 5 and 10 concurrent users executing this unix script for a steady state time of 30 minutes is also working fine even through response time degrades to 4 secs.
With 20 concurrent users, unix box with 4 CPUs is 100% utilized and response time degrades to 11 secs or so.
We need to do this through unix script only because it is executed from database tier (oracle reports - rdfs) and java stored procs doesn't allow awt operations (image file creation).
I repeated this testing using a java class which just loops for 2 secs. With 20 concurrent users, it was also degrading to 6 secs or so and fluctuating between 100% CPU utilization.
Any pointers on what we should be analyzing more and how should we try to solve this issue.
Thanks,
AyyappaStupid forums made me change the ``screen name.'' Whatever...
Anyway, it is resource intensive to invoke a new JVM per request. You can do several things but it comes down to the fact you will want to keep ONE JVM running in the background awaiting requests to do work. These requests can come from several mechanisms, such as polling a database table, sending requests over a local TCP socket, listening in on a Unix fifo file, etc, etc.
When the shell script is exec'd, connect to your JVM (for example) by opening a socket to it, enter your request for work, and wait for the response, the JVM app will listen and accept socket requests, thread off and process and then return data. Something in this form will be substantially more scalable that what is currently being done. -
Upgrade to 6.5.4 and 100% CPU usage
We recently upgrade a 1.6G Essbase db from 5.0.2p13a to 6.5.4p2 - Windows 2000. We ran the 5.0.2p13a db for 5 years quite successfully and now on 6.5.4 our calcs have improved but our data retrieval has slowed down to a crawl. When user's are extracting data (via excel) our CPU is quickly crawling to 100% usage and staying there - task mgr shows essbase.exe with 100% usage and restarting essbase frees up the CPU. We have 8 logical cpu's and more than enough juice to handle things. We have a source db with a transparent partition to a db that user's access.Our db has tons of dynamic calc's and we turned off the dynamic calc cache and picked up a bit of speed but still not the response times of 5.0.2p13a. We notice some time improvements when hit the source db versus the partition copy but still not getting acceptable response times.Is there an undocumented config setting or anything we're missing that may help us?? We getting frustrated trying to find the slowdown.

Safari launches with spinning ball and full fans and 100% CPU web processes
Exactly the same issue on Macbook Air and new iMac both running Safari 5.1 and Lion 10.7.3
When I open Safari it does not open a page, it just shows a spinning beach ball and shortly after the fans kick in and the activity monitor shows 1 webprocess at 99 - 100% or sometimes 2 web processes at 50/50% all coming from the User. When I inspect the process it says it's "Parent Process (Safari 450)"
When I quit safari the web processes stay at 100% and will only stop when I quit them in activity monitor.
I have reset Safari but no joy.
Firefox etc works fine.
The only update I ran was a 1Password update but they say it's not them.
Any help would be appreciated. It's driving me crazy.Solved..... I used App Zapper to delete Flash and Safari is working fine again!

Memory Leak and 100% CPU in slapd process when using Open Directory OS X 10.8.5
Has anyone seen the slapd (LDAP daemon from OpenLDAP which OS X Server uses) run away when running Open Directory? We've tried disabling replication but it doesn't seem to matter. The slapd process will start up and take up about 400MB and then at night will consume all the available memory and crashing the server.
Any thoughts? Any benefit in upgrading to Mavericks' Server app?
Thanks,

512MB of RAM and Widgets...can it make the system completely freeze?
Noticing a very sluggish response on my Mac Mini I realize that memory is an issue with MS Office and such using Safari with iCal in the background.
My Mac does a complete freeze, no force quit no toggle when I hit F12 (widgets) retrieving widgets while an app is running will freeze the system it has occurred twice in one day.
I use a maintenance tool to run cron jobs, optimize safari, updated prebinding, check S.M.A.R.T disk and all is fine.
Looking for more avenues...
I am on the fence on adding more memory because of the processor chip and wanting to go to Leopard shortly..
I may just have to backup and live with this problem...The folder and question mark at startup is an indicator that no valid MacOS install was found to boot from. Usually it means the system can't find the internal drive or the internal drive wasn't correctly recognized. In a normally functional and correctly configured Mac, this is a rare thing, but it can happen if, for example, the system is usually booted from an external drive, but the external is disconnected or powered down.
However, it can also be caused by an error in the system management controller, where an SMC reset will usually resolve it. It may have been this in your case, since although you may not have intentionally performed an SMC reset, the disconnection of power and other devices is essentially the same thing!
Just check that the startup disk preference pane has the internal drive selected, and as long as there is a valid MacOS install on that, this problem should not recur. -
Finally, after 3 mb's, 2 psu's, 2 sets of ram and 2 cpu's - the system is up!
Hi all,
After almost two months of waiting for rma'd replacement parts, my new NLE is finally up and running!
As it turned out, it was the new processor that went bad - all along. But i feel i need to correct some of my incorrect assumptions in my previous posts regarding the problems getting my new system to work.
My original original problems with the P6T - post http://forums.adobe.com/thread/494850?tstart=30 - indicated a bad interrupt controller, unfortunetly, i failed to realize that the hardware diagnosis pointed to the processor. Then i replaced the P6T with two GIGABYTE GA-EX58-UD5's - post http://forums.adobe.com/thread/504671?tstart=30. So, i spent the next two months suffering through constant power cycling and replacing every part until i was left with the processor as the only part that was not replaced.
While there are users out there that had and are having the same symptoms i had with the ASUS P6T and the GIGABYTE GA-EX58-UD5, in my case, the actual cause was different and not a problem with the motherboards. I did have a few bad sticks of bad ram that caused the mb to not post as well.
Had i properly deduced that the processor was the problem, as the initial hardware diagnosis indicated, i could of saved two months worth of headaches.
Anyway.... I now have the following stable working system:
processor: i7 920
motherboard: GIGABYTE GA-EX58-UD5
ram: 12gb of Crucial DDR3 1333
graphics: GeForce 9500 GT
psu: PCP&C 910 watt
and lots of hard drives.Nados: Glad you figured it out and got everything running now! Congrats.
Charles and Nados: I you both could run the http://ppbm4.com benchmark and send your results to Bill, it will give an indication of how your system is performing. Interesting would be to see the results of Jim Simon, since he is running with 3 GB of memory on an i7-920 and most here are running with 12 GB, so the differences may be telling what performance gain you can expect from the extra memory. For you Charles, it is interesting to see your current system in comparison to the one Nados now has. It will show you what the new system has in store for you.
I started out with 12 GB so I can't tell what the performance gain is of 12 over 6 GB. -
Hello everyone, recently I have noticed my fans kicking into over drive while on a facetime video call, I checked Activity Monitor and realized that Facetime was using over 100% CPU, with the system running at about 10%.
I found that making Facetime full screen, and using the 4-finger swipe to hide Facetime instantly dropped the CPU down to about 34%. However, the video is paused, making this work-around pretty useless, considering what Facetime is used for.
I am not sure if this is because of updates or firmwares, i have all the latest updates, the OS is Yosemite 10.10.1.
If anyone has any information regarding this, or is experiencing the same issue, a response will be greatly appreciated. I have searched on the internet, however I can't seem to find any solutions or viable work-arounds.

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

I'm running firefox 11 on Win 7 Ultimate. For the last 2 weeks it is pegging out the cpu at 100% and this is with 3 tabs open. I close it and check the task manager it stays open. I have to end the process. I then reopen and all is good. It will work for a while but flash constantly crashes in youtube (not saying that is a firefox problem) but I don't get this cpu usage. Using 600 MB RAM and 100% cpu with 3 tab...come on now. So, any ideas what is going on?
Hi laytoncy,

Hopefully this helps! -
I have a 1U Server purchased in August, 2003. The motherboard model is MS-9129, motherboard chipset is Intel 845E ( Brookdale-E) + ICH4. Bios is Phoneix Award 6.00 PG, dated 12/10/2002. We are running Windows 2003 Standard Edition, SP1
The system is currently operating at 100% CPU, with the System process consuming all otherwise unused capacity. Within the System process, an ACPI thread is utilizing all the resources. Our analysis, together win Microsoft Tech Support suggests upgrading the bios to a more current version.
Two Questions:
1) Have you experienced this, and do you concurr with the solution, or do you have a better one?
2) What, and where can I get it, is the most current BIOS? Do you have Installation instructions?
Thanks

Time is of the essence here.I've run a virus scan showing no viruses, and Symantec AV is up to date and running.
I can't get a screen shot, as there is no software on the server capable of getting one, and I can't load anything when it is this slow. Besides, all diagnostics I have, or that Microsoft has had me run, show that it is the ACPI subsystem which is causing the problem. I have disabled all software other than the basic operating system, have assured that the OS up to date and still have the same issues.
MSI's LiveUpdate shows the BIOS to be version 1.0, with the most up to date one for this system seems to be 1.3. Does anyone know how
this translates to Phoenix's numbering system? All the system diagnostic tools I have shows my current BIOS to be Phoenix 6.00. Is the MSI 1.3 BIOS really an upgrade?
Thanks
