Java using up 80% to 100% of CPU

I am using a
Macbook Pro 13 inch Mid 2010 with 4gb of RAM and a intel core 2 duo processor running OSX Lion.
How can i stop java using so much cpu

Please include extension info from '''Help -> Troubleshooting information''' in Firefox's menu

Java uses up WAY too much cpu power only in firefox.

I seem to have found out that firefox is using up to 60% of my cpu power(average of each core). It seems to be a problem with Java and maybe windows 7 64 bit. When I turn java off it's fine and uses maybe 10% tops. But since 2 main sites I use use only java I can't just turn it off.
== This happened ==
Every time Firefox opened
== I moved up from Win XP 32 bit up to 7 64 bit.

Ok I guess you have stumped me, but disabling java in the past did bring down my cpu usage. Cpu usage was no where near as high using that looping radar and this open, around 10 percent or less. As for extensions I only have the java console and skype. I've tried using gmail alone without my usual tabs, also tried facebook(which I thought were the culprits) but cpu usage didn't stay up, only spiked at loading. So I guess it's back to square one...I'm wondering if it's just having a somewhat good amount of tabs open. Last night though was fine when I opened firefox just to see.

Apple Mail client app (version 8.0) using 100%+ of CPU upon using mail drop (13" R-MBP running Yosemite 10.10)

Hello Support Community,
I am having quite the interesting issue. I have read plenty of reports where users' Apple Mail app is using 100% of CPU. This did not start for me until I went to go use the new mail drop feature in Yosemite. I am running Yosemite (10.10) on my 13" Retina - MacBook Pro (flash storage, 8GB RAM, 2.4 dual-core Intel i5) and my Apple mail is version 8.0. I have tried 3 different mail services (2 gmail accounts and iCloud), all result in the same issue. I have also done a complete erase of the hard disk and a brand new install of Yosemite, the issue persists.
As previously stated my mail app is using 100% upon, and only while, using the mail drop feature. If I force quit the mail app and allow it a minute, the mail app returns to using less than 1% of the CPU and the app and entire system resume normal function. Upon attempting to resend the same message that is placed in my outbox the CPU usage jumps to 50-80%. After a few seconds, the CPU usage will sometimes jump higher than 100%, ranging from 130% - 199%. All of these observations were made using Activity Monitor. Of course you can see my frustration, an app using this much CPU stops every process my Mac is doing (using safari, messages, iTunes etc.) - the whole computer locks up. Even force quitting is a difficult process to attempt.
Does anyone have a fix for this? I am at a loss and have no idea what to do. I am a pretty tech savvy guy and have tried everything that I would've thought would fix this. Is there anyway this could be a hardware issue? I don't think so but... all possibilities need to be taken into consideration, even though that one seems outlandish. Upon creating a new user account with a separate user library (but same system library) I figured the OS was the problem. I can't narrow it down to being a specific mail provider, and it can't be my OS since I have now erased and reinstalled 10.10 twice. Thank you!

I have this same issue. It has been driving me insane, Mac Mail uses 100% CPU most of the time I use it, after every time I open the machine, or after a sleep or even mostly after a screen saver has locked me out. It normally settles down after 5-15 minutes, but then happens every time again. It is killing my battery.

CWBufferedAO.zip uses 100% of CPU

This sample program is modified as follows,
CWAO1.UpdateClock.Frequency = 1024
CWAO1.NUpdates = 1024
CWAO1.ProgressInterval = 256
When PCI-MIO-XE16-10 is used and NUpdates is the same value as Frquency, this program uses 100% of CPU and "STOP" button does not work.
Our program was developed for DAQCard-6036E and was intended to use it on PCI-MIO-16XE-10. Because of programming requirement, the stopping process should be taken within 1 second after STOP button is clicked.
Is there any reason why this sample program uses 100% of CPU when small value of NUpdates is applied?

My PC is DELL Precision-620 (2 CPU's) with Win2000.
The sampling rate is 1024Hz so that 256 samples take 250ms. It is very slow operation.
STOP button does not work and some user logics do not work in Progress routine.
Attached a slighly modified program to show you the strange opeartion in Nidak32.sys. Are the Update count
and Time Editbox updated on your PC?

Clementine 100 percent CPU use after quit

after i quit clementine, pause it or stop playback get 100 percent cpu. any ideas ?
when i start clementine from console this is what i get, the second part is after i hit the pause button
Couldn't load icon "clementine-panel"

I only get 100% CPU after quitting. There's a bug report here.
Seems to be something to-do with the nvidia drivers.
Play, Stop, Pause etc. seem to work fine and I don't get any QPainter errors so you've
got some other problems there.

ITunes is hogging 100% of CPU. Tried "netsh winsock reset" fix already

I recently upgraded to 10.5 and iOS5. I had a similar problem to many in the community related to the sync getting stuck in the "back up" portion, so I tried the solution proposed by a bunch of people re: "netsh winsock reset" and I can now sync, but I still have the issue of iTunes and APSDaemon hogging nearly 100% of CPU. Anyone else having the same problem? Any insight would be appreciated. Thanks

I'm having similar problems after the 10.5 upgrade on Vista. Tried the repair option in Control Panel, then uninstalled and did a fresh installation thinking it might have been due to the Apple upgrade installer but I'm still having the same problems. I've got 3gb of RAM but I can't even do something like writing an email at the same time as using iTunes without it beeping at me.

Itunes consumes 100% of CPU 15 seconds after startup

I was using iTunes 8, and experienced the following very annoying problem : 15 seconds after startup, the itunes application starts to consume 100% of CPU, and the application is not responding anymore. If I started to play a file within those 15 seconds, the file continues to play normally, but I cannot stop it anymore, and I cannot work on my PC (as 100% of CPU is taken by iTunes).
I tried to upgrade to iTunes 9.2, but the problem persists.
Any idea what can be the cause of this problem ? It prevents me to use iTunes on my PC.
Config of the PC :
- Windows XP
- 1 Gbyte RAM
- AMD 1.14 GHz

Sorry Itunes 11.0.2

IChatAgent takes more than 100% of CPU

The iChatAgent takes more than 100% of CPU. It works normally for 10-15min with little CPU usage but then takes 100% of CPU and stays like that until I quit/kill the process. I tried waiting for hours to see it might go down is usage, but no, and the cpu fan remains on continuously.
I simply use it for text based chatting, and have disabled audio, video,microphone etc, and still this behavior that I can't use it for more than 15min.
Here is the iChat version: Version 5.0.3 (745)
Macbook Pro/10.6.4/Intel Core i7
I have tried removing ~/Library/preferences/com.apple.iChatAgent.plist as suggested elsewhere, and that hasn't helped either.

Thanks again Ralph.
No, I do not have any add-ons, just out-of-the-box ichat without any audio, video in use.
At this stage unfortunately, I can't continue using iChat as it hogs up the CPU in less than 15min. And that I do not experience any problem with other chat-clients such as AIM or jabber, so switching over to those until there is a resolution.

PCMCIA media card readers - suck 100% of CPU for copy?

Hello!
I've bought two media readers - for camera memory cards - for my Powerbook. They are PCMCIA cards, one is a Sandisk card, for SDs, MMC, and Memory Sticks, among others. The other is a no-name brand for CF cards.
While the Powerbook (10.4.11, 2 GB ram, 1.67 Ghz) will recognize the readers - and the cards I insert - should I attempt to copy anything to or from the card, the entire computer gets thrashed. The CPU usage (Finder, Kernel_task, etc) go to 100%, and iStat Pro has shown CPU load numbers between 15 and 25! What the heck?
At the same time, if I insert either PCMCIA readers (with cards) into my old PowerBook 5300CS (OS 8.5, 48 MB Ram, 100 Mhz), the CPU is not fully used. Ditto for my 2.2 Ghz Macbook Pro and a Belkin Expresscard SDHC reader - in fact, it copies at the card's full speed and uses only a couple of % of CPU. It's running Leopard now, but it didn't have any trouble in Tiger either. That's why I think it's a Powerbook error.
It will happen with either reader, any brand/type of card, and has been occurring for quite a while - since sometime in early 2007. I don't remember it always acting this badly, so it may have been related to an OS update.
Does anyone have an idea of what the problem could be, and any fixes?
Thanks

Hi, N23. That's interesting. It was just a guess, as I said.
Since the beginning of 2004, when I bought my Titanium Powerbook as a new, recently-discontinued model, I've read everything in all the Tibook forums here at AD on a daily basis. Though my memory isn't what it once was, I can say with pretty good confidence that this problem of unreasonable CPU loading only when a CardBus card reader is in use has very rarely, and maybe never, been reported in those forums. This despite the fact that every time someone has posted there to complain that their camera won't transfer pictures to their Powerbook, I've recommended using a CardBus reader instead of connecting the camera. No one, to the best of my recollection, has ever posted back to upbraid me for giving that advice because it didn't work out for them. And this has included lots of people who were running Jaguar, Panther, and Tiger, and a handful who were running Leopard. So I agree with you that the problem is rare and weird.
I don't understand why this is, but I know from experience that some card readers (CardBus and USB; I have no experience with FW readers) can't properly handle cards with capacities higher than 1GB, which of course are much more common now than they were a while back. So I wonder whether a mismatched card and reader might be at the root of the problem for some people who have it. Unfortunately I don't recall exactly what sort of misbehavior occurred when I tried to read a 2GB card in incompatible readers. I know that whatever it was, I didn't check Activity Monitor at the time to see if it could shed any light on the problem. I don't have access now to my daughter's camera card or the readers in question to run any new tests.
I also wonder, without directly disputing your view that pre-Spotlight OS versions might have had the same problem, whether CPU-hogging Dashboard widgets could be implicated in some way. Widgets were often found to be consuming outrageous percentages of CPU cycles in the early days of Tiger. Might there be some widget most people don't have or use that swings into action when a CardBus reader is connected, but not when a FW or USB reader is? Sounds unlikely, but I have no idea. I'd be very interested to hear from anyone who can confirm that the CPU-overloading problem also occurs in Panther or Jaguar, and not just in Tiger and Leopard.

A process named "update.exe *32" and description is "Firefox" keeps using a lot of memory and cpu; the longer forefox is on, the worse it gets. How to prevent?

using Windows 7, firefox 15.0.1
This process uses more and more memory and CPU, sometimes there are several of these processes running. If I kill these processes, it doesn't seem to affect the utilization of Firefox. Then the process slowly starts to use more and more memory and CPU all over again.
This happens all the time, every time I use Firefox.

I do not have a ComObjects folder under C:\Program Files (x86)\Common Files. That is not part of Firefox.
wscript.exe is a utility included with Windows to run scripts at the system level. It generally is not used by major programs. If update.exe is starting up with Windows, you may be able to find the script that wscript.exe is running using [http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx Autoruns].
It definitely sounds viral. I suggest deleting the update.exe file, although Windows might prevent you from doing that until you kill all related processes. And if you have a persistent infection, the file may be restored or re-downloaded.
It might be easiest to seek assistance from a forum more dedicated to malware cleanups such as the following:

Hope you get it removed.

ps>> I want to to use Generics to help it but I don't know how to do it in the right way . Can you you help me?
Thanks
Arunya

regarding your Map/LinkedHashMap, since you keys are String and you values are Objects... you would define you Map using those two as you data type pair...
ap<String,Object>thisRow = new LinkedHashMap<String,Object>();and similar for you List/ArrayList where you putting Maps into...
List<Map<String,Object>> rows = new ArrayList<Map<String,Object>>();for more information on generics read...

CREATING A SEARCH IN JAVA USING MYSQL QUERY

How do i create a seach in java using mysql queries. The search need to be like a good type one, whereby a category is typed and the results obtained via the search system using jtable.
Thank you.

Read the tutorial on [url http://java.sun.com/docs/books/tutorial/]JDBC Database Access.
Read the tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/table.html]How to Use Tables.
Put the two together and you come up with something like [url http://forum.java.sun.com/thread.jsp?forum=57&thread=497641]this.

What is the output of Maya and how does Java use it in animation.

What type of software is used and what input and output files are created in the animation process?
From what I read:
Maya is used to create polygon structures, perform rigging, and it attaches surface textures which are made in Photoshop. Then Maya creates key images or positions of the animation. Next Maya exports an image and a data file to do the neccessary transformations. Finally, Java uses the image and the data file to paint the images and their position based on the game logic's use of the data file.
What have I missed or described wrong?
I also need more clarity on the input files to Java and how Java stores and uses these files. The use of Maya images and files seems different. Is Maya or Java doing the transformations or are they both doing them? How does this work?
Thanks for your help
Jon

Thanks for the explanations. What this means in my situation is that tags are an unnecessary way of spending a lot of time making my file system more complicated, without adding any value whatsoever. Without tags, I can find any of my 3,000 files with a few clicks. (On my computer, Spotlight has cobwebs. I very rarely need it, but it's wonderful when I do.) Now that I know how tags work, I can ignore it.
A human being can only perceive a quantity of seven without counting or grouping; hence we arrange things in structures to keep the number of entitites low on each level. You don't need to count three objects to know that they are all there, but you do need to count twelve objects. Which is why Home Alone was believable. We sort screws and nails in jars and toolboxes have compartments. Even the grocery store has a hierarchical arrangement. You don't find steaks in the bakery section, or breakfast cereal in the produce department.
Some people aren't organized, and that's not a bad thing, but no folder, no tag, and no group is going to change a fundamental personality characteristic.
Thanks everyone for showing me that in my case, there's no point to tags. That saves me a lot of time.

Duration of an Abap Function call from Java using Jco3

Hi guys!
I would like to use this discussion to get some refernces of the duration Timespan of an RFC call from Java to SAP. At the moment, i need at last about 200ms to call the Abap function. I'm just using one simple import and export parameter (so no deep structures). I think that the reason for my poor performance is, that the Java Tool and the SAP instance are not in the same network. So, i hope some of you have some data, how fast an RFC call from Java using Jco can be executed.
greetings, Hannes

Hi Hannes,
I think you have already got the answer to your question - the network set-up you have is probably the bottleneck. Whenever I've worked with Java <-> ABAP and they are in the same network, I've had no performance problems at all.
Does your RFC contain any complex logic or business processes? Are you able to try and call something that does nothing, say it just accepts an input string and returns it straight away as an export. Do you have any scope for testing with your Java tool on the same network as the SAP system?
Cheers,
G.

Passing pl/sql table to Java using Oracle JDBC and vice - versa

A small article on the given topic with sample code and comments, to make code crystal:

Tapash,
I have seen people using Rosetta in almost all projects in previous years, frequently in couple of projects. I was not aware that Rosetta is an internal thing, anyways if that is the case y oracle is shipping rosetta jar file to customers?
