Kernel_task consuming 1-1.5 GB memory always on my MBPr 13"
My MBPr 13" kernel_task is consuming 1-1.5 GB memory always. It does not matter what running on computer. I did a fresh install OS install. Didn't help. From the moment of starting the mac it takes 1.2 GB memory. Is it normal? Is there any way to fix it? It still under warrenty.
Is it normal?
Yes.

My mac is slow, the movies run slowly, the kernel_task consumes 463,3 MB of memory, how can I fix this?
The problem started a few weeks ago with a small decrease in speed, and the videos now crash while the sound remains normal. When I open the Finder or any file it seems that I'm opening the windows with the hourglass spinning. I've already cleaned temporary, removed everything that was saved on the table, I made up for the mountain lion. I have a Mac 27-inch, 3.06 GHz processor Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3, ATI Radeon HD 4670 256 MB, Software OS X 10.8. With space on the HD.

Kernel_task consumes a lot of real memory
(I do not speak english, all translated by google. Sorry.)
The process "kernel_task" of my MacBook Air is always occupying a lot of "Real Memory", always up to 1.5GB. Why? How can I solve?
Thanks and sorry bad english.Read this document.

Kernel_task is using a lot of memory
I am curious if it is normal to have Kernel_task take 1.8 GB of memory? It seems to be the consistent reason as to why our server is running slow? Thanks for any help....
This looks like the solution, but I cannot get the commands to work. When I enter the command to make a command of /et/rc.server using the root login, it says:
-sh: $: command not found
How should I enter this command using terminal? thanks, I am really new at this, but I am doing my best to learn. As an aside, is there a site that helps getting started with terminal?
As always, thanks!!
You can make the following change to /etc/rc.server to improve performance in this situation. This is recommended only if your server has 2 GB, 3 GB, or 4 GB of RAM.
Make a copy of /etc/rc.server with this command:
$ sudo cp /etc/rc.server /etc/rc.server.bak
As the root user, open /etc/rc.server in the text editor of your choice.
Locate this line in /etc/rc.server:
sysctl -w kern.maxnbuf=90000
Change the number 90000 to 20000, so that the line reads:
sysctl -w kern.maxnbuf=20000
Save the changes made to /etc/rc.server.
Restart the server. -
6280 Main Memory always full!!!
I am a HONG KONG guy. I brought a 6280 phone for 2 weeks, after install java game the Main Memory always full. I did all unwanted things in the Main memory but the result still..............
I phoned to HONG KONG NOKIA customer hotline. I followed the steps but the bug wasn't fixed. I wasted 3 hours for waiting in HONG KONG (Mon Kok) NOKIA CARE center. Just want them receive the phone & fix it. The phone could not be repaired in an hours since there was overcrowded Let See how bad is it!!
The staff said many 6280 had same problems. But nobody reported to headquarter.
I think would it be possible to upgrade firmware at home like Pocket PC, computer mother board & display card etc.? Software errata are common in complex electronics product. Fix bugs via the internet can be reduced the cost in support & maintenance. Never waste customer’s time & company resource.Sorry for the link was broken.
Let See how bad is it!!!

What's consuming the app server heap memory?
Dear all,
I keep getting the "java.lang.OutOfMemoryError: Java heap space" error in our environment, I tried to remove the BAM from the Jboss, and the error disappear for some times, but it appear again recently, while we only changed one line of script in one of the form. (i.e. I don't think the error is caused by changing code)
So, I would like to know where can I find some information about how the memory is consumed in ALC? Because we only have 2 workflow running, although one of them is heavily used.
Here some information about my environment.
- ALC 8.2.1 with no sp
- Using the default Jboss as app server
- Using the default MySQL as Database
- Only 2 workflow running
- While 1 of them have around 4 - 8 request pre week
- And the others will have around 60 - 80 request pre day (i.e. around 490 pre week)
Here listed some points I think may affect the memory and I want to know for sure:
1) Number of variable used in long-live process (i.e. More variable = more Memory used)
2) Number of operation used in long-live process (i.e. More operation = more memory used)
3) Number of track record of long-live process (i.e. More track record = more memory used)
4) Long-lived process vs Short-lived process (i.e. Only long-lived process will keep consume memory because short-lived process will only load on call?)
5) Number of long-lived process still running (i.e. If we send a assign task to notify the user the workflow have been approved, and the user never dismiss it, it will turn out to consume the app server memory because it is still in the running stage)
6) Old version of the same long-lived process will use memory even no active workflow? (i.e. Because active long-live process will load up into memory?)
Thanks in advance
Regards
BillDid you tried to increase your heap size in jboss server . try this and i think it will help you in solving this problem .
if u want to know how to increase the heap size:
go to bath of ur JBoss "D:\Adobe\Adobe LiveCycle ES2\jboss\bin" as example.
scond find the Run file and open it in Text File
find a line which is responsible for heap size ==>>"set JAVA_HEAP_ARGS=-XX:PermSize=128m -XX:MaxPermSize=192m -Xms1024m -Xmx1024m"
close it and restart the server again and test your problem.
put ur line to be like what i wrote 1024 means that 1 giga for heap of jboss.
if the problem still appear for you then your Memory doesnot of because memory heap size -
Kernel_task consumes a lot of CPU
Hello!
I have MacBook Pro 5,5 with Mac OS 10.6.8.
It always slows down during charging and periodically when it works on a battery.
I have analyzed threads with Shark and it shows that AppleIntelCPUPowerManagement::~AppleIntelCPUPowerManagement eats ~80% of CPU (total 200%).
When I took system to sleep mode then waked it up, all works fine for some time (10-20 seconds), but then it again slows down.
Resetting SCM doesn't help.
How could I solve this problem?Fixing kernel_task overloding your computer!!!
Use this at your own risk. It worked for me.
Basic Procedure:
1- Click in the apple logo on the upleft corner, select "About This Mac".
2- Click in "More Info".
3- Click in "System Report".
4- Take note of "Model Identifier".
5- Create a new folder called "Recovery_Kernel_Task".
6- Select Macintosh HD/System/Library/Extensions/IOPlatformPluginFamily.kext
7- Click the mouse right button at that file and select "Show Package Contents"
8- Open the folder Contents/Resources.
9- Look for the Model Identifier in step 4.
10- Move the file to the folder you've created, if you need to restore the file.
11- Check the folder in step 8 has 49 files instead of 50 (original files).
12- Restart the computer and be happy! -
Kernel_task using 16 Million Terabytes of memory - what's causing this?
According to Activity Monitor kernel_task is using 16,777,216 TB of virtual memory.
Obviously, there is some (overflow?) bug somewhere (is that number the maximum allowable memory on a 64-bit system?), and Virtual Memory doesn't really mean much in the real world, but is there a way to track down what is causing this, given that kernel_task going wrong can bring down the whole system.
This reappears after a restart - and in fact for the first time in memory my computer locked up a few days ago, so I'm wondering if there is a connection.
ThanksYou have a Mid 2010 15-inch MacBook Pro and your log is showing a problem with the NVIDIA graphic card.
These MacBooks have got a defective NVIDIA graphic card that may cause unexpected restarts, black screens, kernel panics... See > http://support.apple.com/kb/TS4088
Fortunately, Apple is repairing all of those MacBooks for free, so make a backup of your data and take your MacBook Pro to an Apple Store or reseller -
Kernel_task keeps using more and more memory, threads. How do I fix this?
In Activity Monitor, kernel_task (PID 0, User root) doesn't take up much CPU, but has a huge number of threads open. It also has nearly 400 MB of real Memory, and over 4 and a half GB of virtual memory! This is slowing my computer down immensly. I tried restarting the computer, but it didn't help. Any tips on how to fix this?

Large amounts of virtual memory are not abnormal. All that means is that the system has pushed a bunch of recently used data off onto disk to free up ram for other processes. If the processes you're running collectively need more active memory than you have installed in the machine or if you're boot volume is almost full things can slow down dramatically, but otherwise the size of virtual memory is not all that relevant.
pid 0 on my machine has 95 threads open, 700 Mb real memory, but only 49 Mb virtual memory. 4.5 Gb of virtual memory sounds excessive and my guess at a cause would be some third-party app or plugin or some such with a memory leak. As a diagnostic, try restarting in Safe Mode and see if the problem is still there. If it goes away in safe mode, then you'll to have to tell what 3P processes you normally run. -
Hi i recently re-installed arch and last time i've created a swap file that works perfectly, but this time i followed every step on the wiki but the swap memory use is always at 0. Even if the ram use is over the 60%
Anyone has the same issue?

What can I do if kernel_task is using a lot of memory?
Is it safe if I quit the process, and what would happen if I do it. Also I have a 4GB memory what can I do to use less? Thank you.
Some processes are critical, but many can be interrupted without any problem.
You can monitor your ongoing processes by going to Applications/Utiltities/Activity Monitor; pay particular attention to Disk Activity and Network. To interrupt a process, highlight the process, and tap "Quit Processes." This will interrupt or stop the runaway process. -
Nokia 5800 - phone memory always full
got my phone yesterday from prepay mania, i hav an 8gb memory card in it btw, whenever i go to the menu i get messages saying c: phone memory full, please delete some data. sometimes it doesnt let me access particular features such as "settings" and even returns me to my home screen
my question was how do i move all my future downloads and all the stuff on my phone memory to my memory card, so i wont get these messages coming up all the time
Message Edited by roshan93 on 08-Jul-2009 08:57 AMif you have installed applications, uninstall them and reinstall them but this time choose the memory card as your main destination (the application should ask where do you want to install it). Also, if you have configured an email account, make sure you choose the memory card to store your emails (go to the messaging/email application, select options - settings - other and where it says memory in use select E: Memory Card (instead of phone memory). Finally, if you have been using the Web application, go to options - clear privacy data (select cache and cookies).
If none of these options solve your problem, then do a hard reset (after backing up the phone, of course)

Automator consumes all my Mac's memory
I've created a simple Automator action that:
Asks for Finder Items (multiple)
Sets the PDF Metadata
When I run this, it works fine, but Automator starts eating up memory, to the stage where I can't run it against more than 10 items at a time without quitting and relaunching Automator. Is this a known problem, and if so what can I do to fix it?when you publish an ical calendar in ical via .mac, that published calendar can be subscribed by others, or you can view it on the web, and it will be "read only". so that is quite normal.
if you want your two macs to share ical calendars and be able to edit/manage in both, then do not publish, just have both of your macs registered with .mac and sync all the data you want to sync, including ical. to sync go to .mac sync preferences in your system preferences.

i have a nokia 6233 when i try to change the theme of the phone i have message not enough memory i have deleted most files and nearly all my pics to have more space but still have same message why is this how can i solve this problem anyone out there in the know please please help
The reason is the Theme you're trying to apply is to large for your phone. Most .nth file larger than 1,5 MB cannot be applied on Nokia s40 3rd Edition, so you can either edit it with Nokia s40 Theme Studio, or remove any MP3 ringtones included with your theme (most of them have large size, thus making your theme larger than normal)
