CPO on Activity Monitor over 100%

I run Power eTrade Pro, a java based application with a continuous internet feed, and experience periods of over 100% CPU activity according to Activity Monitor. During those periods the program is frozen. This didn't happen with 10.4. It happens both on my G5 Quad and my Intel iMac 2.4ghtz. I sent a general suggestion to Apple about it but I thought I would post here as well. By reducing the amount of information being displayed I can manage the problem but change that up and boom, frozensville. When no information is being fed, like when the market closes, the CPU usage drops to near nothing. Maybe Java in 10.5 could do a better job of managing CPU usage like just slowing down a lot near 100% but still run. Can't imagine I need 8 cores to make this work. Especially when it was fine in 10.4.

Somehow, this problem has resolved itself.

Running 10.8.3 on an Intel iMac 27'. The Finder keeps grabbing over 100% of the CPU which seems to stop me from opening any folders. Only quitting the Finder from Activity monitor resets it to normal. Any ideas?

Nope, I don't have a "/Users/charon/Library/Mobile Documents" directory, let alone anything underneath it. Is that like an iCloud thing or something? I tend to avoid the Apple-supplied services when I can (I don't use iTunes either unless I can help it).
As an update, as of about two days later this problem seems to have solved itself. Possibly sleeping and waking did something to it (though that seems unlikely given how many times I rebooted), or else there was just some long-*** kernel process that finally worked itself out. But my system CPU is back down to normal and the cursor freezes are gone.
??? it is a mystery! ???

IMac using 100% of the CPU, but no processes in Activity Monitor show usage over 3%. What's going on?

This iMac is about 5 years old. It has the 2GHz Intel Core 2 Duo processors, 2GB RAM, and is running 10.8.5. After rebooting the machine, CPU usage is low. After about 30 seconds, when using Activity Monitor, CPU usage bumps up to 100% and stays there without budging. When viewing the CPU tab near the botom, % User is about 95+%, and % System makes up the other 5%. They change slightly every second. The problem is, if I sort my Processes by % CPU, the largest user is Activity Monitor with around 2.3%. Everything else is at 0.0%. So there's something weird going on causing the CPU to max out and run hot, but I can't figure out what's causing it. Checking for applications to force quit doesn't show any issues, and repairing permissions doesn't do anything. Is there any way to figure out what's going on? I read about how to reset the System Management Controller, is this something I should do? Thank you for ANY help, it's driving me crazy!
EDIT: I figured it out! Browsing All Processes, I'm running a folding@home program, but I thought I uninstalled it! The process is called FahCore_a4. Is there any way to prevent it from showing up on boot? I want to get rid of it but I deleted the applications!

Be certain to check that you are viewing "All Processes" as opposed to "My Processes"

A process by the name of avgcmgr is loading the CPUs by up to 100 percent. At least 5 of them have appeared on the activity monitor. I've removed them with forced quit but they return! How do I permanently get rid of them? CPUA temp is now 194F.

Hi Ray-
I'm having the exact same problem and have searched the web for hours looking for a solution (multiple spawned avgcmgr processes that consume cpu).
Did you find any solution?
Thanks so much!

When I set up Contacts on iCloud, Contacts on my Mac consumes about 100% of a CPU, per Activity Monitor. Does that make sense?

I don't think this should be happening, but I haven't been able to find any reference to such a situation in Apple Support or on Forums.

I'm trying to do this. I unchecked Contacts, restarted my Mac and lo and behold, Contacts was rechecked! I unchecked it and checked Activity Monitor. By the time I returned to System Preferences, Contacts was rechecked. This happened 3 times. Now it has remained rechecked, AddressBookSourceSync is consuming over 90% of a CPU (mostly over 95%). I'm letting it go for about half an hour. I'm debating whether to let it go and see if it settles down (no evidence that it will). CPU time is over 30 minutes now. I think I'm going to quit (or Force Quit) AddressBookSourceSync, follow the suggested steps and see what happens.

Mountain Lion 10.8.3: Dock shows 100%+ CPU in Activity Monitor

I upgraded my 'early 2008' MBP from 10.8.2 to 10.8.3 last week. Memory use seems to have increased with no real change in application usage — .CPU utilization seems similar, too. I have been watching Activity Monitor + vm_stat to see if I could identify any issues. I just noticed that the Dock process shows 100% CPU utilization in the detail section — even though the Activity Monitor summary stats show plenty of idle CPU cycles available. Swap activity is minimal — this all makes me question the validity and/or accuracy of the detailed stats shown in Activity Monitor. Any input or comment from the community?
TIA...
P.S. Activity Monitor screen shots are below. And no, I'm not running Parallels as per prior discussion https://discussions.apple.com/message/15596756#15596756 from 2011.

My $HOME/Library/Preferences folder contained only two com.apple.dock.* files:
com.apple.doc.plist w/current date timestamp
com.apple.doc.plist.KBPCAn with two-month old date timestamp
Detailed examination of the com.apple.doc.plist parameters seemed to be correct with nothing abnormal.
The killall Dock command suggested by Kappy seemed to address the 100%+ CPU at first, but then it returned.
Three consecutive full system shutdown/restart cycles seems to have eliminated Activity Monitor showing the Dock process running @ 100%+ CPU after 24+ hours of operation. No changes were made to the content of com.apple.dock.plist. My best guess at this point is that my system's Dock process may have had a memory leak-type issue that is neither traceable or reproduceable at this point.
The Activity Monitor issue variance (Dock process detail @ 100%+ CPU despite the summary record showing idle CPU cycles available) isn't explained. It seems to me that the sum of the detailed Activity Monitor records should match the summary pie chart information presented.
Thanks to Kappy for the input and suggestion. Further comment/discussion WRT the Activity Monitor issue is most welcome...

HELP- Over 1 Gigabyte of "Swap Used" in Activity Monitor RAM!

Hello,
I have a late 2013 Retina Macbook Pro running Yosemite, with 8 Gigabytes of RAM. I noticed that on the Activity Monitor it shows that I have over 1 Gig of "swap used"! In the screenshot it says 974 megabytes, which is still bad. I've heard that it's okay for your memory usage to be high as long as the memory pressure graphic is green, but I've also heard that swap shouldn't be used, especially not 1 Gig of Swap.
I'm not running any high intensity programs, only Safari, Spotify, iMessage, Mail, iTunes, Chrome, and things of that sort. Why would it be so high?
High swap used is a bad thing, because it uses the SSD and shortens its lifetime. I don't even know why I would be using it, as I'm not running anything very intense.
What can I do? What should I do? Should I re-install Yosemite from scratch? Does anyone know what app could be making this happen in the background?
Kernel-Task and WindowServer are the processes that are using the most RAM that I don't know anything about. A screenshot is attached.

Safari normally uses over 1 GB of ram even if I only have a few tabs open.. often I have videos loaded, though. I think I'll clear out cookies, cache of safari and then possibly re-install Yosemite.

Why does the process Report Crash stay active and take up over 100% of the CPU?

In addition to window-server taking an inordinate amount of CPU, I am seeing that the process "Report Crash" is sucking up 102% of the CPU and occasionally goes down to 90%. ***? What IS Apple doing these days? Their products are getting worse and worse!

Select that process and kill it in Activity Monitor, see if it comes back.

Activity monitor shows Logic CPU use @ 100% randomly

I'm running a light session (6 audio, 2 instruments) and after I initiate playback, the rainbow ball appears and the activity monitor shows high CPU activity. The problem seems to occur particularly if I click anywhere in the arrange window while playing. Any ideas?

30,000 to over 100,000 pageouts of memory is this normal?

Hi, I have 8 gbs of memory in my Mac Pro. I notice that sometimes istat nano will show alot of page outs used up.
After restarting my computer, It usually starts at 300 pageouts, then it goes up to 30,000, then over 100,000. This can happen within a day of restarting my Mac or a few days.
These are the applications that I have open: Iphoto (45,000 pictures), Itunes , calendar, Quicktime X, Apple Mail, Finder, Safari, Preview.
Is it normal to have that many page outs with those apps open? Sometimes I don't even use my Mac much and it still goes up. Thanks guys

Depends on how much installed RAM you have, number of open applications, and the sort of work you are doing. By itself Pageouts is not an indicator of anything special other than over the course of time the computer has accumulated that total as a result of various applications having to page out data to the hard drive. A more significant indicator is the value in parentheses shown by 'top' in the Terminal. If that number is positive and increasing then it means you do not have sufficient RAM to accommodate all the applications you are running concurrently. See:
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.

Mac goes over 100 percent cpu usage

As seen in the picture, the game called 'runescape' which i was playing reached 171 percent cpu usage on my computer. My computer never crashed from playing this game but crashes alot while playing Dota 2, once when I crashed from dota 2, the computer lagged showing my activity monitor which showed that dota had 100.1 percent cpu usage. Is this a problem of the game or the computer? Multiple friends of mine have played this game and never once crashed on it.

It is a problem with games in general: they use a lot of CPU power (and heat the CPU up correspondingly). Over 100% is not very spectacular, because modern CPUs have 2, 4 or 8 cores, and each has a maximum of 100%. If you have a 4 cores cpu the run escape is taking almost 45% which is a lot.

Itunes spiking my CPU well over 100% - any genius got some time?

Hi there,
Ongoing problem with my iTunes 7.5 hammering my CPU at well over 100%. This happens regularly every 5 - 7 minutes and is quite annoying. I used activity monitor to copy the activity as it was occurring. I hope there's a genius here who can decipher what my issue is. Please it's driving me crazy!!!
For clarity, I repair permissions regularly, I update after a safe waiting period, repair permissions again, restart computer, use Mac Janitor for day, week, month, repair permissions again, restart computer, etc...
My computer runs extremely fast when iTunes is off. Everything grinds to a halt when iTunes starts to spike.
Also I checked the discussions and followed, with no luck, all the prior recommended fixes.
Any help would be greatly appreciated
Thanks

What is this Wine that takes over 100 MB of memory running on root on my computer?

What is this Wine that takes over 100 MB of memory running under root on my computer?

The only apps I have installed since purchasing are Mac Keeper and the most recent version of Caffeine.
Also, wine is running by itself, and it is there going when I first turn the computer on. I can shut it down through activity monitor, though.
When I look at the process heirarchically, though, it shows up.
The process heirarchy looks like this: launchd -> AntiVirus -> wine and nothing is running under wine.

Activity monitor inconsistancy - what is real virtual memory size???

When I look at my activity montior system memory screen I see real and virtual memory in MB (with the largest at about 500MB). As in my previous post I see a VM size of >240GB. When I go to the File menu and hit Save... and then look at the resulting processes.txt file I see that the virtual memory is now listed in GB. The real memory is consistent with what I see on the activity monitor window. See below. What's up? Which virtual memory is real and which is "virtual"?
Active Memory: 1.47 GB

Ignore that. The method it's calculated works as following:
1. You have the Finder and Safari open.
2. Both programs and no other ones use the content of a single block of data. This block takes up 2MB of RAM or swapfile space.
3. The block is counted as 4MB in the VM size entry because it's being used twice.
Expanding the scenario over many processes and blocks adds up to a VM size figure which is far larger than the actual amount in use or the combined total of RAM and swapfile space.

Activity Monitor % User and % System do not add up

Looking at my iMac i7 Activity Monitor/ All Processes/ CPU I find that the % User and % System do not add up to showing the correct % Idle.
For example, a recent screenshot shows % user = 0.81, the % System = 0.41 and % idle shows 61.25. The CPU usage graph show nothing going on and the Process Name list shows nothing unusual.
This constantly changes - sometimes the figures add up to 100% but usually the % Idle can be anywhere from 40% to a correct 98 - 99% based on nothing of any consequence running.
I look at the Activity Monitor on my MacBook and % Idle shows correct addition and a constant 98 - 99%.
What is going on?
Thank you.

This afternoon, it will be an entire week without a crash on my Squeezebox system!
Totally removing Intego VirusBarrier X6 from my main computer (iMac i7) finally lets me enjoy my music again.
The main problem is that X6 does not provide feedback as to what it is doing so the user cannot adjust the settings. In other words, no specific message as to what X6 just prevented.
As a crash can occur anywhere from 10 minutes to 8 hours of play time, hit or miss setting adjustments waste an amazing amount of time. This has been going on for a year with the frequency of crashes escalating.
I had already entered all my music devices on the Trusted List and had set up rules for all the ports that Squeezebox uses. Still crashed.
There is no reason why Logitech and/or Intego engineers cannot provide security setup instructions. Unfortunately, Logitech only shows security help for PCs.
Well the nightmare is over. Amazing what free time I now have.
The next three paragraphs are for Squeezebox owners and may be of some help if you are having problems:
A crash (for me) is defined in many ways. The worst crash is when the Squeezebox device shuts off and only pulling the electric plug will revive it. Another crash shows itself when the next song only plays for about 1 second and goes to the next song endlessly until the device shuts off. The Logitech manual says move the device closer to the wireless point when this happens but if they are connected by ethernet cables, this advice is useless. Another crash is when three units are synced and one of them suddenly is no longer in sync and playing a different song.
Crashes can occur when units are in sync or not in sync. Connected wirelessly or by ethernet. And when a crash occurs, the loud 'crunching' noise that occurs is not kind to the speakers.
BTW, if some devices are in sync, make sure these devices are connected the same way - either all wirelessly or all by ethernet. If you don't, you will experience sound lags of about 1/2 second. A very annoying echo effect.
