vlad1966 Posted January 29, 2009 Share Posted January 29, 2009 It seems like no matter what kernel I try, OS X takes almost all 8GB of my RAM. The biggest culprit seems to be kernel_task. I've tried Voodoo 1.0 kernel, XNU 9.4, right now using vanilla with 9.6 system kext on XxX 10.5.6 PPF1 and it's always the same problem. I knew OS X was a memory hog, but didn't think it was this bad. It's ALOT worse than Vista! What can I do to fix this? On my previous boot it took all except 30MB of my RAM, then I got a kernel panic. HELP!!!!!!!!! PS: It seems that when I start doing any kind of disk-intensive activity, that's when kernel_task starts eating my RAM. Like now (& the last KP I got) I'm using CCC to clone my boot drive to my RAID setup, and kernel_task is using 317MB of Real Memory, 2.3GB of Virtual RAM Link to comment https://www.insanelymac.com/forum/topic/150050-all-8gb-ram-being-eaten-by-leo/ Share on other sites More sharing options...

What you are seeing is the correct behavior these systems will use all available memory for data or caching whatever it needs it for really then once it is full it will start paging out the parts of it not needed anymore. This results in better performance due to the greater chance of what you need still being in memory instead of having been swapped to disk. What can I do to fix this? On my previous boot it took all except 30MB of my RAM, thenI got a kernel panic. It is not broken so no need to fix anything the kernel panic on the other hand indicates something is going wrong with your hardware somewhere, it should have told you what exactly it was in the error message judging by your sig you have a pile of stuff in the machine so it could be any of a number of things...

Like now (& the last KP I got) I'm using CCC to clone my boot drive to my RAID setup, and kernel_task is using 317MB of Real Memory, 2.3GB of Virtual RAM Since here you mention what you were doing when it panicked I would say there is a good chance the raid is the problem.

vlad1966 Posted January 29, 2009 Author Share Posted January 29, 2009 MacUser2525, thanks for all the info - much appreciated. At least now I know that this behavior is normal for OS X.

530sCheapMac Posted January 29, 2009 Share Posted January 29, 2009 my advice is to always start with the most basic options provided to you by the OSx86 Installers, to see the very basic minimum of what your system needs to run, and add things to improve compatibility as NEEDed.
