Our ISP is trying to get a news server going using FreeBSD, and is having
some problems. He's installed inn from the ports collection, but can't
seem to keep the machine running for more than a few hours at a time. He's
tried several combinations of SCSI cards/cables, but it hasn't made any
difference so far.
The most recent crash did terrible things to one of the file systems; fsck
reports files with billions of blocks, unknown file types, and more.
I'm enclosing the kernel config file, dmesg output, and a stack backtrace
from the kernel dump. The kernel was configured with "config -g" and
compiled with "-O2 -m486 -fno-strength-reduce -pipe".
Any help would be *greatly* appreciated; they're trying to use FreeBSD at
least in part due to my bragging about how well it works....
