100% cpu load on file open

Hi,
very recently I have a very strange problem. whenever I open a file dialog on windows with a java program, the cpu load goes to 100% and I have to kill the process. It does not make a difference which java application I choose, it happens with dbvisualizer, freemind or ldapbrowser all the same.
Here's what I tried already:
* uninstall recent security patches
* upgrade from 1.5.0_06 to 1.5.0_07
* kill all running process and services (firewall, clearcase, virus scanner, all kind of other stuff) that are not required to run the machine (and boy was my computer fast, after I did this! lol)
All with no effect whatsoever.
Facts:
* It''s not related to the java program
* It's not related to the JVM
It's somewhere in the integration with windows, but where is it broken, and what can I do, to fix it? Any idea what I could do is really appreciated!
Help :-)

Yesterday I was close, today I found the reason. IT'S SO F***ING STUPID. It's actually another bug, which is only fixed in mustang:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6317789
For some reason I indeed had a shortcut on my desktop to the desktop itself. We have some document management system where you can checkin and checkout documents, and I configured it so to check them out to the desktop, and apparently that program created a shortcut on my desktop to the checkout folder!
Well, anyway, I have all the latestest security patches and drivers now - and also Java is working again. Can I now assign the duke dollars to myselfi? :-)

100% CPU load but no clue in thread dump, EP. Win a bottle of champagne...

Hi,
We are suddenly facing 100% CPU load in our EP cluster (5 x 8-way Xeon multiprocessor machines). We have a serious performance problem that is burning a lot of our time and causes a lot of stress for over 3 weeks now.
We have taken tens of thread dumps from Application Nodes.
- In none of the thread dumps we see the Finalizer thread
running.
- From the garbage collector log we see that full garbage
collection runs occur very rarily (once an hour).
- We use the compacting garbage collector.
- In a lot of thread dumps we do not even see our own portal code in the stack traces of the threads!
- In Windows Task Manager we see the jlaunch.exe processes
consume all available CPU time.
- Portal users see a blank portal page when the CPU load hits 100%. When the load goes down again, things return to normal.
- There are no errors logged in any of the log files of the portal. We checked all of them. We expected a log full of errors somewhere but nothing even remotely interesting was found. Windows Event Viewer shows nothing either.
- The amount of sockets in CLOSE_WAIT status is < 10 on every machine in the cluster.
This forces me to conclude that something in the jlaunch.exe executable consumes the CPU time. This raises the following 3 questions:
- What does the mystifying jlaunch.exe do besides executing java.exe ?
- Why is the Java virtual machine launched by a custom executable like jlaunch (What is it that cannot be program med in Java) ? Can it be GZip compression ?
- If the problem is not caused by jlaunch.exe, then it must be caused by the JVM. What activity, invisible in thread dumps, is performed by the JVM that can cause the high CPU load ?
Our development- and support teams are desperate. All suggestions are welcome. The person that comes up with
the solution to our problem gets a nice bottle of champagne.
Regards,
Chris Twigt

Hi,
- What does the mystifying jlaunch.exe do besides executing java.exe ?
This is so that the startupframework can connect more easily and take control of the JVM in some situations
- Why is the Java virtual machine launched by a custom executable like jlaunch (What is it that cannot be program med in Java) ?
I assume when SAP release their JVM (in the next major release), that will be called directly.
- If the problem is not caused by jlaunch.exe, then it must be caused by the JVM. What activity, invisible in thread dumps, is performed by the JVM that can cause the high CPU load ?
Loads of thing, but there should be clues in the thread dumps. (the reason why your code is not in those thread dumps is that your code is only active during the processing of a particular request, unless you have a service, afterwards there are no trace of it as the thread which does the processing goes back to sleep)
I've experienced a similar situation with a an 6.40 portal, and it was then caused by the following:
1. User A comes logs in and sees that some cache timeout has occured , therefore it issues a SQL query which does a full table scan on a table of approx. 1 GB (on of the UME tables)
2. User B comes in just afterwards and also sees that the cache timeout has occured, and issues the same SQL query as User A
3. User C .... and so on untill the query from User A eventually finishes
So
1. Check database. Any big queries running ?
2. Check file activity, are there a lot of writing ?
3. Check network activity, especially to the state controller which is the weakest link
4. What about portal logs ? Any activity during the hang ?
Also, please provide one of the thread dumps for further analysis..
cheers

100% CPU Load

Hi,
I've been running the trial of Lightroom on Win XP, Athlon XP 3.2Ghz w/1Gb RAM + 2 hard drives. 1 SATA drive (all my images) and a 10Gb IDE disk for the database.
I've read some of the FAQs and switched off every process that I don't need (AVG, iPod service etc). However, I've found that lightroom completely takes out my PC quite regularly (BSOD) and when it doesn't do that, it either crashes itself or sits there, doing absolutely nothing but taking 100% CPU load. It seems to be doing something in substrate.dll but I've googled and not found much information on it.
anybody have a similar experience? any ideas? From the odd bit of time I've had with the tool, I think it will be great, if only it didn't fall over at every opportunity.
cheers,
Matt

I have upgraded to Lightroom 1.1 and am having severe problems. I am running Windows XP SP2. When I try to access a photo in Library or Develop, it hangs for minutes "loading." Windows Task Manager indicates 100% CPU issues whenever I try to do anything. I see by this thread that I should increase the swap file (which for Adobe Photoshop CS3 is located on another disk on my laptop as hdd space is limited on my primary hard drive). I cannot find this setting for Lightroom. Also, should I try to delete all photos in the Catalog and reinstall all of them to improve performance? I am quite desperate. I did not have these problems w/ Lightroom 1.1, even with limited hdd space. Please advise.

Start x11vnc -- X uses 100% cpu load

Hi.
I switched to arch64 and today I first used x11vnc and it is extremly slow. First I thought about the proxied connection but after looking into top I found X is using 100% cpu load. With arch32 everything worked as normal. Don't know whats the problem - any advices?
Regard, Andreas

Hmmm, I switched from official nvidia driver to xf86-video-nv and now works much better. I'll try it again with nvidia but not today...

Update 3.6.17 to 4.01 fails on add-on sequence (100% CPU load)

When updating Firefox 3.6.17 to 4.01 the update process fails in the add on updating phase (loses activity). Afterwards starting Firefox results in close to 100% CPU-load and no progress at all.
Since FF 4 no longer provides for a safe mode start, I can not check a FF4 start-up without his add ons. And removing the addon before the update was never required in Firefox before.
I noticed that the Microsoft NET Framework assistant 1.2.1 in FF3.6 is replaced by version 0.0.0. for FF 4 (looks for 3.5 SP1). Perhaps this MS jump in version is the root of this problem?
Extra: either disabling the NET Framework assistant, or moving to the addon to version 1.2.2. before updating solves this problem. Maybe this is not an addon problem after all, but FF4 instead?

BT stack file TosBTMng.Exe causes 100% CPU Load

I'm also facing the problem that the Toshiba Bluetooth Manager (TosBtMng.exe) very often starts looping and causes a CPU load of 100%.
This happened with older versions of the Toshiba Bluetooth Stack and current version (5.1.0.12).
The affected system is a Tecra S1, internal BT-Modul and Windows XP SP2.
Installation of the BT-Stack went well and the notebook will boot succesfull while BT is enabled. I also checked for hidden COM-Ports and other hints found in this forum, no success.
The lockup seems to happen at different times. Sometimes just after are reboot, clicking on the BT Tray symbol with the right mouse button. Then the context menu is shown just as white area, no entries. It may also trying to connect to an already paired device. If I kill the process with the task manager I can restart and it continues to work for some time.
As found in another thread here I have enabled API logging of the Bluetooth Manager and found the following while connecting with the Nokia PC Suite to my mobile Phone:

A new COM port is successfully created (COM23), and a few seconds later the CPU Load of TosBtMng goes up to 100%, but no API calls are performed. And if you wait long enough the phone gets connected and data can be transferred. However, very slowly.
Probably due to the high CPU load a next COM (COM24) port will be created sometime later and this process is then repeated again:

Maybe this helps to locate the origin of the CPU load problem of the Bluetooth Manager.
Thanks

I was having the same problem, and it turned out to be the Data execution prevention settings. I had turned on (System->Advanced->Data execution protection) the execution prevention for all programs, causing TosBTMng.exe to max out one processor core all the time. The solution was to add TosBtMng.exe to the list of exceptions and restart. I'd looked high and low for a solution - hope this helps someone else!

100% CPU load in Projects view

Hi all,
my aperture is acting strange for a while now. If i start up my main library the CPU load rises up to 100% in the "Projects view". If i change to a subset of photos the load goes back to normal. But as soon as i change to the projects view again the CPU load rises again. During all this there is no activity shown in the activity window.
Sometimes aperture stops acting like this. But only sometimes and after a while. By now i couldn't figure out why all this is happening, and when it is stopping.
I already did a rebuild of my while database and also deleted the cache files as described in several blogs. A normal workflow is not possible with this behavior.
Maybe someone has experienced something familiar and can help
Im working on a 2008 Macbook with 4 GB of RAM. My Library has about 77.000 images in it. Aperture version is 3.1.1.
Thanks,
Stephan

This is good, isolating the problem is the first step, it appears the problem is to do with the library not the application.
You mention in your original post that you did a rebuild of your database, did you follow any of the other First Aid steps laid out on the Aperture 3: Troubleshooting Basics page? The Repair Permissions & Repair Database options.

Gdm is running dbus-deamon with 100% CPU load

Hello Guys,
I have installed an Arch with Gnome yesterday (I am comming from Fedora). I am very happy with my installation, nearly everything works fine. Now i noticed, that my CPU load is super high. So i used top to check whats going on...
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
536 gdm 20 0 13108 1380 1136 R 100 0.0 126:25.88 /usr/bin/dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3
So gdm runs the dbus-daemon with 100% load. Whats goin on here? I have checked the wiki/forum and could not find anything.
Thx for help!
Some notes:
DAEMONS=(dbus networkmanager hwclock syslog-ng netfs crond)
gdm is started by systemd.
UPDATE
Hmm, seems to be a bug in dbus... The web is full of reports.

From the sound side try enabling and disabling msi for snd-hda-intel module (4 combinations to test). Another bothersome parameter is often snoop. Look for quirks for your hardware in alsa source code. Also you might want to disable your ~/.asoundrc for the time being. If you want to set MID as default card, you can use the recommended modprobe method in the meantime.
I would test another browser first though.

(Linux, SL510, NSLDEGE) No processes, 100% CPU-load reboot 1% CPU-load

I have a very big problem:
I bought a Lenovo ThinkPad SL510 NSLDEGE (2847-DEG) on this (german) website with no installed operating system. At first, I installed Ubuntu GNU/Linux 10.04 which worked excellently at the first view.
But then the big problem appeared the first time: suddenly my CPU-load grew from ca. 3% to 100% (because I started an editor or I opened a new firefox-tab) and I couldn't use my ThinkPad in any way, until the system crashed and I had to reboot. After the reboot all worked fine.
This problem appeares intermittent and I always see my last chance in rebooting the entire operating system. I've already tried different Linux-Distributions, but this did not solve my problem. And I've already tested my random access memory (RAM) with Memtest86.
Thus, my question is: Do you have an idea, what could cause this problem? What could be the reason for my CPU-crashes?
Greetings, Mekeor

I'm sure that this is not a Linux-problem!
Furthermore I wrote a bug report on launchpad (the ubuntu bug-report-website) here: https://bugs.launchpad.net/ubuntu/+bug/615792 . And here is my first forum-entry in the german ubuntu-forums (forum.ubuntuusers.de).
Besides this phenomenon, I think, is a specific characteristic of my Model (SL510, NSLDEGE)!

Firefox 15.0.1 stops responding (100% cpu) when a link opens in a new window.

Whenever I click a link that is designed to open in a new window Firefox goes straight to 100% cpu usage and I have to go through the Windows "end now" sequence to close the program. I've tried opening one of the links in a new window but I think it was done in java not html (not sure if all the links are java when this happens as that's the only one I've tested). Not sure what details someone might need but this is on my Mom's older laptop with Windows XP Media Center Edition Ver. 2002 Service Pack 2. Hmmm just saw the SP2 will try to update and see what that does though I don't think that's the issue.

So what is happening or not happening now ? The problem computer is your Moms, but I assume your own computer works ok. Have you tried that on the same internet connection as your Mom uses & visiting the same sites?
Also try Internet Explorer. If that is also very slow the problem may not lie with Firefox.
I suggest you try the Firefox Reset feature on your Mom's computer,
* BUT first of all
**make a note of the software extensions that are in use, and bookmark their download and support sites.
** back up the Firefox profile [[Back up and restore information in Firefox profiles]]
* follow the instructions in the following article, after reading the caution about what will be lost
**[[Reset Firefox preferences to troubleshoot and fix problems]]

Adobe Reader 9.4-1 cause 100% CPU load on EL40 system

Hi,
when starting Adobe reader 9.4-1 on a Enterprise Linux 4 system the cpu load directly goes up to 100%
This happens on EL40 update 4, 5 & 8
I´m using gnome.

I had the same problem on a RHEL4 system, I think starting with 9.3.1. The system requirements say only RHEL 5 is supported so I just uninstalled 9.3 and didn't look into it further.

[workaround] 100% CPU load in GTK2 applications

I'm having strange issues with my GTK2 applications, namely Thunar and Thunderbird:
The gui is extremely slow and causes 100% cpu usage (just one core) for the process running Xorg.
For example, if I move the pointer between two buttons in Thunderbird I can watch the mouseover-effect being drawn - it takes almost a second!
No errors in Xorg.0.log, dmesg or xsession-errors, though. I'm using the proprietary NVIDIA-drivers and my system is up-to-date.
Any advice?
Thanks

I compared the 1.12.2 vs 1.12.8 pkgbuilds and it seems that the culprit is the missing patch: cairo-1.10.0-buggy_gradients.patch
Seems definitely a packaging issue:

High Cpu Usage when file open in Illustrator 9

Hey guys, have had a few problems lately when an EPS or AI file is open in Illustrator 9.0 cpu usage sits between 50 - 100% and clicking around the program is in general very sluggish. All boxes with problems run Windows 2000 SP4. These arn't slow machines either, about 3GHZ dual core, 1GB ram. I know Illustrator 9 is old but it's being used in a business environment so upgrading is not really an option. Thanks in advance for any help.

By "lately" do you mean this is something that started happening recently?
If so, can you remember any changes (updates, service packs, other software, etc.) you might have made to your boxes recently?
Are you updated to 9.0.2?
If not, it's worth doing, and here are the pertinent links:
9.0 to 9.0.1

When writing DSC-tags, MSDE causes 100% CPU load

I have a number of shared variables configured to be logged in the DSC database. When I'm writing to these repeatedly the SQL-server (MSDE) loads the CPU with 100%. Why is that? Even when I've stopped, it “hangs” at 100% for quite some time. Eventually this stalls all other applications and the whole machine. What is DSC doing in the SQL-server? Is there a way to configure the behaviour?

Why are you concatenating an empty string to all of your strings?
You don't need to have multiple index arrays. Use one index array and resize the bottom of it downward. You won't need to wire up any indices either. By default, the top one will be index zero, and each one below that will be +1 the one above.
How does it behave when you run it with highlight execution? Does that give you an idea where it is hanging?
Also, your connection string as several backward apostrophe accent characters rather than regular apostrophes. See here.
