Hey folks, Has anyone had their kernel task manager (the scheduling and swapping manager for the operating system) go so beserk that it sucks down nearly all the cpu cycles? I've searched around on the net and found suggestions like:
. reset the PRAM . reset the PMU . deleting extension caches . cleaning out system and user caches I've tried all of these, as well as starting in single-user mode and running fsck (equivalent to using the disk utility to repair the boot drive). My computer is still taking over 10 minutes to get from the login window to being 'functional'. In fact, it can run so slowly that it takes, oh, about 10 minutes to even log in. If I look at top (the command-line equivalent to the activity monitor), I see that the kernel task manager is using between 150% and 180% of a cpu (my mac mini has a dual core, so it has 200% of a cpu inside). Things can get so bad that logging in becomes nearly impossible because the machine seems to miss keystrokes when typing passwords. This happened earlier this summer, also, but somehow resolved itself after 4 or 5 hours of cussing, restarting the machine, and attaching and detaching various external drives. I think I found a common thread between the misbehaviors: before both cases, I mistakenly pulled the power cord from the back of the mini when trying to unplug an external drive, because the mini's power cord looks just like a firewire cable. In both cases the computer was running and was (clearly) not properly shut down. Any clues about how to troubleshoot this?
