    I've seem to noticed after the last update was pushed or the last itunes update (i don't remember which) that my swapfile is getting thrashed majorly hard. I ran "top" and nothing looked out of the ordinary. the trashing got so bad, I was waiting for my hd to finish its vm swap while my window animations froze midway. the only way to solve my problem right now is to delete the /var/vm/swapfile* and reboot file which isn't a very good solution. the weird thing is sometime to get past the slash screen on boot sometimes I have to reset my PRAM.

    My other guess is my hard disk maybe is going bad, which means it a bitch to replace the hd.

    I have powerbook 12" dvi with 768 mb ram and 13.7/37.7 GB HD

    anybody got any ideas?

    if it happens again, I'll post when it does start thrashing again.

    You're not paging. Not with those stats. The swapfile is not getting used at all. You should just have one swapfile in /var/vm.

    I average around 5 swapfiles on a 2GB PM G4. That's a lot of swapfile usage.

    If your system starts acting up again capture the same data and also an "Ls -l /var/vm" for reference.

    It might be 10.4.2 or the last security update. I've noticed a bit of oddness as well. I'm hoping 10.4.3 fixes it.

    You should collect baselines every so often and then post the last one before it happens and then what it looks like after the thrashing happens.

    I keep getting "stuck" processes. apparently the lag is caused by the processes waiting on other processes to come out of deadlock. I believe they are waiting on the hard drive I/O.

    FYI: dnetc is something like a folding program. it suppose to suck all the cpu speed and never giving me a problem. although there was just an update. I'll trying running without it for awhile. i still think i have a hard drive problem.
