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
Dagfinn

  • Firefox using almost 100% CPU - hogging resources - hanging

    After several hours of operating Firefox starts using almost 100% CPU - with peaks of 100% occurring in rapid succession - FF hangs until CPU useage drops below 100%
    Followed recommended troubleshooting as recommended on this site:
    * Started in Safe mode - no problems occurred.
    * Disabled all extensions; Plug-ins left operating.
    * No replication of problems.
    * Enable 1/2 of extensions up to Flashblock - restarted - seems ok
    * Enable most remaining extensions
    * (There are 3 Java extesnions - only enabling one) - again seems ok
    * Some hours later - problem reoccurred. Each time CPU useage peaked at 100% (according to Task Manager) the Firefox Window flickered & was unresponsive.
    * Deleted cache - no change
    * Disabled recently added programs - no change
    FF opens and closes normally & completely. '''Problem only seems to occur after FF has been operating for some time'''
    This has occurred intermittantly before but has become chronic over the last few days. Apologies if I've been repetitive or explained poorly - FF has hung several times while typing this.

    No issue for me, after 4 loops my CPU load was around 18%.

  • Plugin-container.exe is using 90-100% CPU - even while running Firefox in safe-mode. Can I fix this?

    I am using fire fox 5.0 (after using 3.6 for what seems like forever) and the plugin-container.exe has been sucking up my CPU power like a vampire. It had been doing that in 3.6 but not as much. I figured if I upgraded the problem would go away, but no, it has not. After reading some other similar posts, I ran Firefox in safe mode with no plugins running and sure enough after browsing for a bit it started running slower and used 90-100% of my CPU. Is there any way to fix this issue? Or am I doomed? Thanks in advance for any help you may be able to provide.

    That's supposed to show you the problem isn't Firefox, don't know how successful that actually is. You can delete it so that it starts up again. Susggest restarting Firefox when you see it has used about an hour of CPU time as the next hour of CPU time will take shorter to get there and you will be locked out.
    Also see this -- the solution on all the items seem to fix a lot of problems with the places.sqlite database.

  • ReportCrash using over 100% cpu after opening photoshop cs6

    Currently running Mavericks on my macbook pro & just started noticing a problem. I'm sure its been there for a while, judging by past performance of photoshop, but just now caught it in activity monitor.
    After I launch photoshop CS6, AM automatically shows ReportCrash as using upwards of 100% cpu, which explains why my computer seems to be dying when i'm working in the program.
    As far as I could get with this problem on my own is checking concole to see what might be causing the process to appear. Not sure how to fix the problem though, which is why I come to the forums seeking guidance!
    thanks in advance for any help!

    Same thing is happening to me. Seems like it started about a week ago, fan is running a whole lot now. I'm not saying it's the cause but the "top" utility shows /System/Library/CoreServices/ReportCrash running at 103% - 105%. Weird.
    Changes: In the past 10 days Software Update delivered new versions of OS X 10.9.2 and iTunes 11.1.5, and I installed and ran DiskAid 6.5.3 and evasi0n7-mac-1.0.7. Also, Chrome began to hang several times a day in the past week so I removed it and re-installed it, which seems to have solved that problem.
    Anybody else hearing the fan a lot and seeing these 100%+ utilitizations lately?

  • Premiere Pro using over 100% CPU

    When I open up Premiere Pro, it is using about 6.5% CPU. I can cut, move around in the timeline and add effects ok. But when I play the video (even if its just one track with no effects) my computer starts running very hot and Premiere starts using over 500% CPU. the CPU cores heat to the 90s Celsius. Below are some specs, let me know if you need more to help answer. Thanks!!!
    MacBook Pro
    OS X 10.9.4
    2.2 GHz Intel Core i7
    Memory 4 GB 1333 MHz DDR3
    Adobe Premiere Pro CS 6 - version 6.0.0
    Here's the CPU and temps before Premiere plays anything...
    Here's while it is playing through a video...

    First of all, I strongly recommend that you update to 6.0.5. You'll reap the rewards of many bug fixes. I won't venture whether that alone will help with the temperature.
    As you probably know, video processing is one of the most processor-intensive activities you can ask your computer to do. Exactly how hard your CPUs will be pushed depends on at least four factors:
    The type of video, namely the codec. Those that use interframe compression are much more processor-intensive than intraframe compression.
    the resolution, or pixel dimensions, of the video: higher resolution = more pixels = more work
    the number of layers in your sequence. And be aware that if you're using nested sequences, you need to include all the layers in each of them.
    effects. Some effects like scaling and color correction require a lot of processing.
    One key data point you left out regarding your computer is the graphics card. A card that supports GPU processing will take a lot of the stress off of the CPU. From the system specs you provided, I gather you're on the Late 2011 MBP. If it has a 6750M or 6770M with 1GB of VRAM, then it's supported for CS6, but not if you have the 512MB version. (Here are system requirements for CS6: System requirements | Adobe Premiere Pro)

  • FSEVENTSD using 90-100% CPU after updating to 10.6.4

    My iMac, previously running fine, is now running very slow. After reading some things here and elsewhere, I tried shutting down Spotlight indexing using Terminal (don't recall exactly what I did). That did kill Spotlight but I am still having the problem. I also reinstalled Snow Leopard from my original retail disc and then did the combo update. Still no good. I bring up Activity Monitor and FSEVENTSD is constantly running at 90-100%. This has persisted for a few days now. FYI, I do have both Firewire and USB 2 drives connected. I did seem to notice that the problem may have started when I reconnected the Firewire drive after doing the reinstall. It may have been a coincidence though.
    Please help. This is killing my productivity since even my mouse is running slow.

  • Lync 2013 Web APP browsers using up 100% CPU

    This problem only began this week. Lync Web App is spiking CPU usage, at times up to 100%. Primarily with the presenter speaking. thus causing the speaker to sound robotic. Is anyone else experiencing this issue.

    Hi Rene,
    As your problem happens when presenter speaking, I suppose the problem is related with Sound Card driver.
    Please try to uninstall the Sound Card driver and install the latest driver.

  • Browser not responding, often using up 100% CPU

    *tl;dr My web browser (and often other programs) freeze and Activity Monitor shows they're using a large amount of memory.*
    I've been having performance problems with my MacBook for a few weeks now, with single programs causing my computer to heat up, freeze and make noise. Although I don't know what the cause may be, I've ordered 2 more sticks of RAM that will, hopefully, make things work smoother. But I'm still curious as to what is happening and why.
    I'm using Webkit (webkit.org) right now, and yesterday I ran Onyx in an effort to alleviate problems like this, (a poor page ins/page outs ratio, specifically), but that, evidently, may have had the opposite effect. Within the past hour that I've had my computer on, this has happened twice. I have only had Webkit open- no other applications. This has started happening a few weeks after I upgraded to Snow Leopard, perhaps that has something to do with it.
    Thanks.

    Thanks! I've got to leave the computer for the night, but rest assured I'll try both of your replies and label them accordingly.

  • Web browser processes use over 100% CPU (OS 10.6.8)

    Hey, I know this problem has come up a lot in the last couple of years, but I've looked everywhere, at every thread and possible solution to my problem and none have ever worked, so as a last resort I'm going to just straight up ask bout again and hope I'm missing something.
    So whenever anything on my browser is moving, wether it be Flash, HTML 5, Java or even an embedded video, on every browser I've tried from Opera to Safari and every time it will put two or three processes related to the browser up to 60%, usually amounting to over 120%. I have tried doing a fresh install of Snow Leopard, which only softened the problem for a small while. This problem, and a couple others started happening after the 10.6.8 update was installed. I have never installed Safar Extensions, I have fixed permissions, cleared caches, binned files, tried running Safari under 32-bit and 32-bit Rosetta.
    Nothing works. After 20 seconds of a youtube video my macbook will freeze and ask me to hold down the power button. If I download the video through activity and play it in VLC it's fine. If I play it in Quicktime it's fine for 20 seconds and then the video stutters and slows right down before the audio stops and Quicktime refuses to play anything unless it's closed.
    Among other problems caused by the update: Alt 3 is no longer hash, it just turns my cursor into a crosshair temporarily and MDS/MDworker sometimes randomly decide they're going to join in on the rogue processes for a while. I'm so close to having to sell a bunch of stuff in order to get a laptop so I can finish my uni course, it's particularly horrible knowing that I rely on my macbook for all my university work and gigs yet it's been letting me down so much.

    Oh, I posted this to the Macbook forum as it's ambiguous whether the update caused a hardware/software confliction, since a fresh install of Snow Leopard did not work.

  • Facetime using 100+% CPU?

    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.
    Below is my MBP configuration
    Macbook Pro early 2011 2.3GHZ i5
    4GB 1333 MHZ DDR3
    Startup Disk Samsung SSD 250
    Intel HD graphics 3000 384 MB
    New MacbookPro battery, few months old.

    Another information :
    if I run two java program on the same time (using same instance of eclipse), the two javaw.exe each use exactly 50% (if nothing else if running).

  • Itunes 8 using 100% CPU on one core.

    Hi Guys,
    Since today Itunes seems to be using up 100% CPU on one of the two cores. This happens shortly after i started it - for example when i play a song.
    After a few minutes it will be reactive again and then i can choose another song - after which it will hang again. It also hangs when changing for example from Films to Music. I have the idea that it happens when i click the Music library - but am not sure. I disabled AV for the itunes library folder - but that didnt change anything. This has been working fine until today. I even uninstalled and re-installed version 8. The only thing that might be related is that when i upgraded to ver. 8 i used the update function in itunes - which didnt work as well - left me with some unusable shortcuts etc. But the app itself was working.
    OS is vista.
    Just saw that this is for the store only - Moderators please move if possible.

    Anyone experiencing this--or have any suggestions on what I could look at to see what the problem might be?

    I had this problem with mount. In fact asking the system for shutdown would set a live lock on a mount process taking one core.

  • Firefox constantly hangs and freezes; uses 100% CPU during the freeze.

    Almost spontaneously, Firefox would freeze and become unresponsive. During this time, every Firefox window is whited-out and do not respond to any input, and the Firefox process uses up 100% CPU. All active content running at the time of the freeze, if any, continue to function as normal (Videos continue to play, web applications providing audio notifications send them as normal, although any visuals are now not visible as the browser windows are frozen. The sound continues uninterrupted, however.)
    Freezing may occur at any point. Even when the user does not interact with Firefox, it may still freeze. Freezing persists with all addons and plugins disabled.
    The freeze would last between a few seconds to a minute, and subsequent to the freeze, Firefox always resumes responding as if nothing had happened. While it does not result in significant losses, the freezing is extremely inconvenient and may occur as frequently as once every ten minutes.
    The freezing symptom is universal across all versions of firefox between 5 and 8.0a2.

    There are at least four similar topics here about this problem and I have clicked the button that I too have the problem on each and every one of them.
    This is the first time in years that Firefox has given me a serious enough problem to render it unusable.

  • Ocspd - 100% cpu

    Lately i'm having some trouble with my CPU going to 100% at random.
    Using iStat menu's i could see it was a kernel task using about 100% cpu.
    So i checked the logs and noticed every time my Mac went to 100% it was because /usr/sbin/ocspd was started. As far as i could 'google' it, this has something to do with networking.
    I'll add my network setup to be complete:
    Airport Express configured as WDS main (connected to broadband cable modem)
    Airport Extreme configured as WDS remote
    Mac Mini connected via wire to Airport Extreme
    Harddisk connected to airport extreme via USB (airdisk)
    And finally a Macbook (the one with the problem) connected wireless
    Can anyone give me some pointer to resolve this random cpu hog.

    You can view the man page for ocsp here.
    Use Activity Monitor to force quit the daemon. That may be all that's required. However, if it continues to hog CPU time, then you may have a corrupted cache file or a bad preference file. You can try this to start:
    Delete caches to resolve some problems:
    Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN after each commandline:
    /sbin/fsck -fy
    If you receive a message that says "*** FILE SYSTEM WAS MODIFIED ***" then re-run the command until you receive a message that says "** The volume (nameofvolume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way.
    If you were successful then enter:
    /sbin/mount -uw /
    rm -rf /System/Library/Caches/*
    rm -rf /System/Library/Extensions.mkext
    rm -rf /Library/Caches/*
    reboot
    I suggest you print out the above to be sure you do not make any errors when entering the commands. When in single-uwer mode you have 'root' access, so it's important that you not make any mistakes.

  • 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,
    Ayyappa

    Stupid 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.
