arthur5005 Posted May 13, 2008 Share Posted May 13, 2008 I was wondering if anyone knew how to trace what might be causing kernel_task (a general OS process) to become a HUGE process hog and bring my computer to a sluggish state indefinitely (well until a successful restart). I'm thinking it might be some of the vmware daemons from the vmware fusion installation, but I can't be sure. I can't narrow it down to anything I see in my logs, and it doesn't happen very often, sometimes my system will be running flawlessly for 3 or 4 days, sometimes only 3-4 hours, but it at least gives me a good 3-4 hours before ANYTHING might happen so this becomes a HUGE annoyance to find, and when it does happen, my USB dies completely. I have a wireless USB option, so I can't quickly google anything that it might be related to in my console. And it takes forever to restart my system when it does happen, if I just shut it off with the power button before a full shutdown is successful, then system starts back up with the same 70-90% usage by the kernel_task process. A successful shutdown must happen for this problem to go away. I think it might be flash related as well, I recently noticed recently it's happened when a lot of flash has been loaded into safari, but again, really difficult to narrow it down. Is it possible to see how that process is being affected at all so I can best diagnose what's causing kernel_task to be such a heavy process bound task at random? AMD Sempron 3400+ Nforce 560 MCP 65 (I'm pretty sure) GeForce 7600 GS 512 (ROM Bios flashed and modded) Best Regards Arthur.

gordo Posted May 19, 2008 Share Posted May 19, 2008 'bump' I don't have a solution but I do have the same problem so you're not alone. I don't have vmware installed so, at least in my case, it's not a culprit. Sometimes I start out fine and kernel_task takes off for some undetermined reason. More often it is pegged at about 80% right from the first login. I've tried unplugging all the peripherals I can (usb and firewire) and disabling in bios onboard sound etc. So far I can't isolate it. Running Kalyway 10.5.2 on a badaxe2 motherboard which people report is basically compatible. I have tried vanilla as well as sleep kernels.
