    System hangs unexpectedly


    Hello all,
    i am facing a serious problem with the Linux system i have, which is
    SuSe 7.1 (Kernel Ver. 2.4.0-4GB) With ReiserFS version 3.5.29.
    The system had 1 GB of RAM , 2 Nos. P-3 800 CPU, , Intel L440GX
    motherboard.

    The /var/log/messages log file doesnt tells much. only that theres
    some garbage in when the system gets hang.
    i m pasting the log when the system got hang and the log just after
    reboot.
    ##Start of the log###

    The load at the time when the server goes into hang state is not much.
    at the time of the above hang condition, it was

    ok, your system is hanging?
    From the part of the log file that you have pasted, it look's like a lot of custom script's on the system? are they essential? Have you found a pattern to the system hanging? ie everytime (x condition) then (y happens)? How hot is the CPU?

    What have you tried already?

    You have a old kernel. try to update it if you can, and see if the problem still are there!

    If you look at the code real close, you can read "FUXORED" in it....
