    SubjectLinux 2.0.27 kernel crashing
    I have been experiencing problems with my usenet news server lately and I
    think I finally found the cause, and hopefully someone here will recognize
    a solution. What is happening is the server crashes, OS and all, between
    12-24 hours of uptime while receiving a full usenet news feed. I have
    pasted below the last part of the kernel messages that syslogd reports. It
    looks as if every minute or so I get the EXT2-fs error on a particular
    inode, and finally leads up to the kernel crashing. I find that the kernel
    crashes after about 4-5 hours after the errors start.

    Here's the system:
    Pentium Pro 200Mhz
    256Megs Ram
    Linux 2.0.27 (RedHat 4.0 installed)
    Adaptec 3940W SCSI controller
    2 Seagate 4.1Gig Baraccuta (one on each channel of the contoller)

    I'm hoping someone here can give me a direction to go here... I have
    thought that maybe the drive is going bad? I have 4 more 4Gig drives that I
    would like to put online, but I need to have the problem resolved first. If
    you need more info PLEASE let me know.

    Thanks for your help,
    -Rob
