kernel_task high memory usage

Try modifying the spotlight settings: Kernel_Task is taking only 430 MB for me.

Same problem here. iMac late 2007 (eagerly awaiting the new Mac Pro…). It is bordering on unusable. I'm holding out for the Mac Pro, otherwise I might have reverted to 10.8. For me, reboot ”fixes” the problem for a few houres, but not more.

not quiet the the same problem but kind of. kernel_task uses over 100% of my CPU.

Of course my RAM also goes up high but not as dramatic. can't feel a slow system but I'm worried about the fact using permanant a core for the kernel_task

same problem with the memory management....when i use imovie my free memory is zeroing and i have problems with performance of my macbook....i have 8 GB memory on a early 2011 macbook pro....

i think the compressed memory is making the damage...

the compressed memory is growing very fast...

Solved for me... I don't know what to do exactly, I tried to deactivate a lot of apps, restart some times, stay all night with the iMac open, and then all works fine. No more memory ups. All apps works fine for me, and kernel_task stays between 0,6 and 1,2GB stable.

Solved for me! perhaps let time to the system stabilize for itself?

Same here.

"kernel_task" is right at the top of my memory column and won't budge.

It remains at approx. 700MB of physical RAM useage and 8GB of VM.

Also after three days without rebooting my pageouts shows 130,000+ even though I have 12GB of RAM and have only opened a few small Photoshop files.

These things never happened with any of the previous OSs for me.

And iconservices is the second item in the memory column and has created files that are many GBs in size in the private folder.

I don't see how this can be normal.

I made a clean install now and I'm having the same problem! after a certain time, the kernel task rises to about 100% CPU and doesn't decrease anymore.

I think it is related to locking the screen with password and screensaver and coming back. it always starts after unlocking.

obvious I can't feel any system slow down because auf the speed of the MBAir but it makes me kind a nervous...

cheers.kg

I'm having the same issue.

Macbook Pro 13-inch Early 2011 running Mavericks, with 16GB RAM and SSD so I should not be having any bottlekneck!

I cannot export any movie from iMovie 10.0 without it crashing due to memory error. After watch multiple times in Activity Monitor as iMovie begins to export, kernal_task will start hogging memory (It peaks at 10GB!) and then it results in a crash of the application because of memory usage being too much. Ironically iMovie itself never used more than 500-700mb. This is ridiculous...I don't know what is going on but this needs to be fixed!

it does not help most the time use rebot to solove this problem.😮

cant find out which task use most all ram (or memory leak) in background, activity monitor wont show you, even you add up all the process used memory.

have tried use purge with sudo, but you will make os slowe to respond, and then ram will slowly run out...😢

This is happening to me too... Kernel_task is using a standard 2GB and spiking to 7 or 8GB ... crashes at least 1ce a day... and causes me to have to rebuild an aperture library of over 100,000 photos... this takes about 5 hours...

This never happened before mavericks.

I am running an intel Core i7 ... Fusion 3TB HD ... 16GB ram.

Someone please help me??

Thanks, Johnny.

yeah i have the same problem since the past two updates of mavericks have the same problems i own a late 2011 mbp and im not able to watch movies cuz they lag a lot without mention the terrible lag while i use design software as photoshop, rhinoceros among others. im pretty sure is mavericks fault i hope they fix it soon cuz if not im going back to pc at least on pc im used to slow computers.

I have the same problem and have since mountain lion. I'm running 12gb of ram with a 240gb ssd drive and every day or two something starts eating memory then my free hard drive space starts getting smaller and smaller till all apps pause and I get an out of disk space error message. I reboot my machine and I have 10 or 12gb of free disk space again and within 6 to 12 hours I'm out of disk space again. Has anyone found a fix? Or have an idea on ways to prevent this? For me it's also kernel_task that's causing the problem. Anyone know what kernel_task is for? Is that the kernel itself?

Here are my kernel extensions

Kernel Extensions:

com.rim.driver.BlackBerryUSBDriverInt (0.0.74)

com.bresink.driver.BRESINKx86Monitoring (9.0)

Could it be either one of these?

Yep same issue here after updating to Mavericks - has been causing headaches over the last few weeks. 10Gb RAM and running virtually nothing - but watch the memory pressure grow and then start moving to Swap.

I have a near new Macbook Air with 8G RAM and just upgraded to OS X 10.9.1 on the weekend - now i am running out of memory all the time. i reboot every half hour. its painful anf kernel_task is always at the top of the memory usage list (currently using 4.68G Ram)

has there been any 'fix' to the problem yet?
