Greetings,

I just had a weird SCSI incident that shut down my news server.  The system is 
new and has been running for about a week with no problems.  All of a sudden 
INN throttles with the following errors:

And that goes on for several hundred lines.  Finally the drive settles down 
but the next time the newsfeed connects the kernel panics.  A re-boot and fsck 
returns everything to normal.

Is this a disk problem or the alledged 946 problems I've been hearing about?

Thanks,

Craig
