Kernel26MM: 100% CPU use, non-stop?

I just installed the latest MM kernel, and discovered that, after half an hour of uptime or so, the CPU usage jumps to 100% and refuses to come back down. Listing the running processes shows me that none of them are eating up that much CPU time.
(Yes, I know that the MM kernel isn't stable. I'm just pointing out what I'm guessing is a bug.)

i was wrong: it does not solve this issue, but it makes it appear less frequent (no idea why)
i'm uploading a -2 release of the kernel26mm package that has magic keys enabled.
if you see kswapd0 running without idling,press [ALT]-[SysRq]-[p] (SysRq is same as PrtScrn (print screen button) - maybe you will need to go to VC first, if you WM catches such combinations) and then do dmesg and see the last part that was added. if it is different to the one i get here:
http://www.ussg.iu.edu/hypermail/linux/ … /0233.html
feel free to report to me or directly to the kernel ML to the thread about it to help the devs find out what's happening.

Some web pages causing 100% CPU use of iexplore.exe since Flash update

I'm having a problem with certain Amazon.com pages hanging my
Internet Explorer 6 using Flash Player 10,0,12,36, causing 100% CPU
use for iexplore.exe and requiring me to End Task to quit. All the
pages effected have an interactive mouseover Size and Color chart
that intially says "Loading" but then says "Select Size and Color"
once loaded. One mouseovers the various color patches and size
options, each time giving item availability in that option. When
the pages hang the IE browser with 100% CPU use that chart never
gets to the "Select Size and Color" point, instead stuck at the
"Loading" status. This happens most times, but not every time.
Sometimes the pages load correctly, after a brief lag as it loads
the chart.
Amazon pages without this chart load fine.
The start of this problem coincides with updating Flash.
I can prevent the problem from happening almost every time if
I can quickly get my cursor into that chart area while the page
begins loading. If I allow the pages to load fully with no
interaction they will hang almost every time.
I have not noticed any problems on those same web pages using
Firefox using Flash Player 9,0,124,0
I also have not noticed any issues with other sites using
Internet Explorer either. (YouTube, QVC, CNN...etc, all OK.)
I had posted for assistance on the Experts Exchange site and
there was some debate on whether the chart was a Java or
Flash-based chart, so initially it was being approached as a
possible Java issue, so I removed all Java versions on the system
and installed various versions, but the same problem persists.
I've downloaded but not run the Flash Uninstaller, as I'm
reluctant to uninstall the Firefox Flash version without knowing
for sure I could install 9,0,124,0 again.
I've downloaded an archived fp9_archive.zip, which seems to
indicate the contained files flashplayer9r124_winax.exe (Internet
Explorer) and flashplayer9r124_win.exe (Netscape) would be versions
9,0,124,0 to install after running the uninstaller.
Can anyone check a few of the links below and see if the
"Select Size and Color" chart is Flash based? If so, would
executing the files listed above install 9,0,124,0 into my
respective browsers again?

could take a look at my initial post and advise if the issue seems
to be Flash related.

100% CPU using LabView 7.1 and DSC module

Seven years ago I used BridgeView and PXI to execute a project, and the results were so good that after that initial system, I installed one more using BridgeView, and three more using LabView 7.1.
BridgeView is working very well, but lately, LabView 7.1 is giving me more and more problems. It all started in a system running LabView 7.1 and DSC on Windows XP, using a PXI-8187 controller with a PXI-1042 chassis. I have two PXI-6533 digital I/O boards, one PXI-6030E multifunction, one PXI-6713 analog output board, one PXI-6602 counter board and one PXI-8422 serial com. board. In may/06, all of the sudden, the CPU went to a 100% use. Since I am running PID's to control a flash-butt welding machine in a steel factory, this was extremely dangerous. I changed the controller and everything went back to normal. It was running fine until december/06, when the same behavior appeared again. This time changing the controller did not help. We increased the system memory, from 256 MB to 512 MB and everything worked fine. But one month later (january/07) the fault reappeared. This time we changed the chassis and from that moment to this time, we are running smoothly.
Application problems were suspect from the very first time this problem appeared, but I was unable to identify the source, if any. I used PROFILE VI's and apparently the write/read tags were taking all the processor resources. However, changing the routines and disabling communications, and optimizing CPU intensive programs never solved the CPU overload.
Until now, I was aware of only one system showing this erratic behavior. But today I went to check another system, with a totally different application. This one is used to measure the thickness of the steel sheet on a rolling mill. Is not so resource-intensive, but the maintenance folks told me that every time they turned off this particular system, they always had problems trying to turn it on.
I was suspecting of a PLC-communication related issue, but what I found turned my alarms on. I turned off the system, which was fully functional, and turned it back on, and there it was, CPU load at 100%!. Is exactly the same problem that I have on the welder. This system has a PXI-8184, a PXI-1042 chassis, Windows XP, one PXI-6030E, one PXI-6713 and one PXI-6533. I battled for 20 minutes to put the system back in normal conditions.
I specified every single board, installed everything and programmed all the applications. The BridgeView applications have never showed anything like this. I am using the DSC (Datalogging and Supervisory Control Module) on both applications, and the Lookout Protocol Drivers are communicating to Modicon PLC's.
Please, I need help to solve this issue. I believe none of your actual Knowledge Base "100% CPU" articles apply to my case...
Thanks in advance...

Thanks for your reply...
Yes, sometimes I have the feeling that the systems works again because some file or database gets initialized after so many reboots.
Intentionally I turned off all the events and alarm logging to disk. Also the historical data logging is disabled. This is done by code, every time the main VI is started. This was included precisely to save CPU processing power. However, I am communicating to PLC's, and of course I have to declare variables inside the citadel database to make the communication possible.
Right now I can't have access to the application, because the mill is rolling, but during the next maintenance stop I will check the database location and size, and I could change the directory location the next time the fault comes up.

100% CPU use making me want to cry with 3 browsers

I am using an Athlon XP 2500+ laptop/notebook with 1gb RAM
and am having high CPU problems with Firefox 2.0.0.3 (no
extensions), Opera 9.2 and IE.7.
I have uninstalled and reinstalled Flash and Shockwave and
uninstalled my AV, HIPS and firewall - temporarily!
The following web slideshow makes any browser reach 100% CPU
and causes the mouse to seriously lag on each browser.
http://www.koat.com/slideshow/news/13245211/detail.html
This high usage is constant, even when the mouse is not being
touched and the page is not moving or playing music, etc.
Strangely, if the controls of the slideshow are scrolled off
the screen, then CPU returns to normal: <10%
So I only get slowdown when I can SEE the buttons that move
on to the next slide!
Can anyone help?

Hi,
Welcome to the Discussions.
This thread, Could it be the Logic Board?, is about the same problem. You may want to try the drive in an external firewire enclosure.

DW.exe 100% CPU use

I'm using DW CS3 on a Dell laptop, XP-SP2, 1gig Ram, 1.6ghz
processor. After 15 to 30 minutes of normal behavior DW starts
using 99% of CPU cycles (according to Windows Task Manager) for 3
to 5 minutes, effectively freezing the system. This can happen
while doing normal code editing, or it can happen when absolutely
nothing is going on. It will then release the system, but when you
click on something, it goes right back into 99% CPU use. It doesn't
seem to be associated with file transfers, but Task Manager does
report "I/O Other" activity as though it's doing something on the
internet.
Any thoughts out there?
Thanks!!!

Are you running an antivirus on this box? Is it scanning
realtime?

External CD/DVD burner sends OSX into 100% CPU use, cddafs.util file

Hi,
I have a LaCie external CD/DVD burner (301484U) which I use a replacement for the SuperDrive that died in my Powerbook 15" DL, connecting by Firewire. Lately, instead of mounting CDs, it causes the cddafs.util file to take up whatever is left of my CPU sending it into 100% use. Ejecting using F12 and using the button on the drive to eject no longer work. I have to turn the drive off and turn it back on again to eject the disc.
I will ask LaCie too but wanted to see what anyone might say here as well. The drive is relatively new, bought in September. Sometimes CDs mount, sometimes they don't.
I'd be happy to supply more info but am not sure what is needed at this point.
One weird thing happened that might be related. Yesterday I was recording a record to be made into a CD using Final Vinyl and in the middle of the recording it gave me a blue screen with two sets of vertical black lines, freezing the machine. I rebooted and all was fine. I ran Disk Utility and other than a few permissions needing to be fixed, all was well. Nothing interesting in the trash upon restart.
Thanks for any help.
Cheers,
John L

It works in the other account so it should be a file in my normal account right? (I misinterpreted what you meant by "doing it".) If it didn't work in the other account then it would be a hardware problem, possibly the power supply, right?
I'll move the CD Info.cidb file to the Desktop as you suggest. I hope that file isn't too corrupt. Over the years I've lost what CDs I've played from problems with that file. (I have actually kept track of most every CD since my first Mac, with the exception of what I've lost from crashes. I use a program or two to read it. A good one is iCDC for example.)

Xtorrent + DirectoryService = 100% CPU use

if I try to start xtorrent the DirectoryService goes nuts and uses 100% of the CPU - I can't do anything until I shut down xtorrent.

Dock frozen, taking 100% CPU, 50gb swap

My dock is frozen and shows 100% cpu use (that is, 100% of one core). It gradually takes more and more memory until I run out of hard disk space. Killing the process does nothing - it immediately comes back at 100% of cpu and starts eating the memory over again. Same with deleting com.apple.dock.plist.
This problem was occuring in 10.8.3, so i tried updating to 10.8.4, which had no effect.
Any ideas?

I had this problem, eventually found a solution - it's to do with Parallels (and maybe VMWare Fusion) sharing Windows applications to the Mac Dock. It turned out that I had quit Parallels, but somehow it had left something about these shared Dock items in limbo. Restarting Parallels got things right again, then disabling the Shared Windows Apps in the configuration of the VMs

Trying to strace to process just kills it.
It might be that the build process is just plain wrong considering USDT use is not documented yet. However, you might want to have a look.

"EMPTY" Virtual Circuits causes the dispatcher proces D000 use 100% CPU

(29th April)
SQL*Plus: Release 10.2.0.1.0 - Production on Wed Apr 29 14:59:56 2009

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
With the Partitioning, Data Mining and Real Application Testing options
Could someone please indicates why the D000 process uses 100% cpu while no XDB action seems to be running? Whe are not using shared server (besides the XML DB usage) and the only value for the dispatcher parameter in the init<SID>.ora = (PROTOCOL=TCP) (SERVICE=<SID>XDB).
update (30th april)
When I lookup the virtual circuits I notice 2 VC without server and waiter address and without session info.

Stop and start of the listener doesn't solve this problem but killing the unix process will do. When I killed the D000 proces a new dispatcher is started (does pmon do this?) and the current shows 0. This workaround is fine on the DVL machine but no sollution on a production DB :-)
Kind regards,

By the way... you just could be unlucky hitting a very rare situation that caused the phenomenon decribed by you. Deamon processes also could arise due too standard JDBC, ODBC or other connection methods. As long as you don't provide Oracle Support with a SR, you will not know if it is actually XDB related or not.
If I would implement XDB functionality in a production system than at least I would:
a) disable automatic memory management by setting SGA parameters manually
b) set the large_pool_size to a appropriate value to support the shared server processes
c) tweak dispatcher and shared server processes to match at least values that represent
   the minimum++ needed processes (= a higher value then needed maximum)
d) set java_pool size to a decent size (250 Mb or higher)
e) set an appropriate PGA setting to support XML fragment handling
f) DISABLE autoregistering database functionality with the listener
   (see amongs others "Registering non-default XMLDB HTTP/WebDAV and FTP ports
   on a non-default Oracle Listener port" - http://www.liberidu.com/blog/?p=116)
g) alter the xdbconfig.xml file with more appropiate timeouts, locking and cache handling.
h) dedicate a specific listener (aka a a listener not called "LISTENER") for shared server
   connection handling (this for management reasons and specific debugging).
i) use version 10.2.0.4.0 or 11.1.0.7.0 for production environments (I know that this
   matches your environment)
j) always enforce that client software matches the database version
   (as in your case 10.2.0.4.0)
k) keep NLS settings on client and database equal and support a AL32UTF characterset
   (IMHO a minimum requirement on the database side)

Finder and loginwindow use 100% cpu with 10.6.8

I recently installed the patch to OS X 10.6.8 and now the finder is very unstable and uses 100% cpu and the loginwindow uses 100% cpu also. Yes I have Parallels 6 on this machine but I already "un-checked" the "show windows applications in doc" option which is the recommended solution. However, this did not fix the problem. I do not know how to determine what actual process is causing this finder / loginwindow issue. I very much appreciate if anyone has suggestion how to fix this problem.
This is on a mid-2011 MacBookPro.
thank you.

TBauer, I had the same problem with 10.6.8 using 100% of the CPU with Parallels 6 installed. The following steps solved this problem for me:
0. Take a screen shot of your Dock if you wish to remember it as currently set
1. Launch Activity Monitor and click on the CPU column so you can see Dock using the CPU
2. Move ///Users/ ... /Library/Preferences/com.apple.dock.plist to the trash
3. Click on Dock and click on Quit Process to stop the Dock
OS X will then rebuild the default Dock
4. Put the items back in the Dock that you want
That solved the problem for me yesterday morning. I've launched Parallels 6 several times now and moved the machine from my work network to home and the 100% CPU problem hasn't returned.
Hope that works for you, too!
I don't think using the combo updater will solve the problem. The problem appears to be a .plist that is generated with OS X 10.6.7 and earlier that contains icons of a larger than Apple documented size causes the CPU looping. Rebuilding the dock.plist under OS X 10.6.8 appears to solve the problem.
Parallels has issued a knowledge bulletin saying they are looking into the problem. On their web site they have another approach involving moving the offending icon out of the dock to solve the problem. I like my solution better but theirs works, too.

Premiere Pro CC only using 30% CPU and none of the GPU

Hi,
I’m very new to video editing (actually I have no Idea what H264, or avi or mp4 or mov is, I just need the video to work) and I have never used Premiere Pro before. Now I'm trying the CC 7.0 trial.
My goal is to achieve the fastest rendering times possible.
Today I have upgraded my PC for maximal performance in video editing:
Intel i7 4930K (12threads)
Radeon 6950 (2GB)
16GB RAM
SSD
I have a recorded video of me playing a PC game in .avi 2552*1348 resolution (2560*1440 monitor without some borders).
I have set export to H.264 and settings to match source (resolution 2552*1348, 30 FPS, Progressive, Square pixels, NTSC, main, 5.0).
But when rendering (no effects, just cutting) the program only uses 22-45% of the entire CPU and none of the GPU.
The best result with this stress was cca 1:1 rendering:movie length. I'm using 16GB RAM, I tried 32GB and 64GB and the stress on CPU and GPU was the same and the rendering times changed only slightly.
I have an SSD and the read write speeds during rendering are 1-9 MB/s so there is plenty of performance left.
Frankly, this 1:1 performance offers Power Director 11 which I have been using so far. (When editing 1080p the ratio in PP is cca 1:2,5, the same as in Power Director.)
So when the disks are idle, the GPU is idle, more RAM changes nothing and the CPU only works on 1/3 its capacity, what is the bottleneck?
I want to use 100% of the CPU and 100% of the GPU and have the rendering:movie say 0,3:1 or so.
What can I change to fully use the processing power of my computer?
Thanks
