    Two crashes in the last 12 hours.

    Here's the log. I don't understand this stuff, but if anyone has any comments that might help me solve the mystery I would appreciate it very much.

    I reseated the ram chips after crash #2

    Thanks in advance.

    I think it looks like the RAM too. Has it panicked after you reseated the chip(s)?

    If possible, try swapping out the RAM chips to see if one of them is faulty. :)

    No OS crashes in 48 hours. I ran Memtest and the ram checked out okay. Could an app be causing this? Firefox crashes most frequently.

    It's rare for an app to cause a kernel panic, but it could be a driver... It's usually hardware though, and remember that a pass on the Apple Hardware Test doesn't necessarily mean the components are all okay. It simply means the tests didn't find anything wrong.

    There is no such thing as a kernal panic with Macs, because Macs Just Work.

    I used a third party app - Memtest. Run in the single user mode, it was able to test 1924 out of 2GB. No issues. The HD is new from Apple. Two firewire external HDs and a USB printer are attached.

    Just crashed again this AM. What other hardware could be at the source of these incidents. They're fairly random.

    Software based tests aren't fantastic at finding faults. Try swapping the RAM sticks out physically and see if it still crashes.

    Are you saying pull 1GB and wait (?), if no KP, then swap and wait again?

    Pretty much. What's your RAM configuration at the moment? :)

    So, any luck with swapping the RAM and running on one chip at a time?

    Okay.

    Now, how's it going running on one chip? Any problems so far?

    Good choice! I'm traveling for the Holidays, and the tools are at home. I'll try your suggestion when I return.

    No KPs since 12/24, so I'm going to sit tight. Thanks for the input.
