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
