    List,

    I need help. I have an unknown process that has suddenly starting
    hogging the CPU on my staging server (RH8).

    I came back from the screensaver, pressed ALT-F2 to open a
    gnome-terminal. Pressed F1 to get a help window (I wanted to look
    something up). As the help window opened, I moused over to a mozilla
    window and clicked the close widget.

    Everything froze at that point. The HDD spun up, and it has been going
    for 3 hours now. I'm very worried. I get some GUI response, the mouse
    seems to be tracking, albeit very slowly like a flip-book cartoon. But
    keyboard and mouse clicks are being consumed or ignored.

    How can I arrest a haywire process that is potentially consuming 99% of
    the CPU?

    CTRL-ALT-Delete is not responding. I just looked up some stuff on the
    mailing list archives for "process hog" and "process hogging CPU" and
    see that X might be the culprit. I'm considering a trip to work to test
    CTRL-Backspace to arrest X, but this might not work as I'm not sure
    about the keyboard.

    The box is responding to ping. But that could be the NIC and unrelated
    to the OS.

    Thoughts? I'm desperate enough to hit the power button. This is very
    upsetting as the HDD may fail if it continues much longer.

    Tim
