        Look to the first error first. It's often what triggered
errors that follows...

        That claims to be a SCSI streamer tape error. You got a
SCSI tape drive?

        It's complaining that it's getting a hardware error attempting
to write an end of file mark on a tape. Were you writing to a tape?

        Yuck... Sounds like the low level SCSI code barfed up an error
the higher VFS layers couldn't handle.

        The error is a tape error. Do you have a streamer tape or not?
If so, you may have a bad tape or the drive may be going bad and giving
you hardware errors. If not, something is really wrong and you may have
a disk drive going bad and triggering bogus tape errors.

        You really NEED to do something about that, at the very least.
The latest is 2.0.38 in the 2.0 line (and 2.2.14 in the 2.2 line) and
things prior to that had some problems... Seems like there have always
been patches and tweaks to the SCSI code. I remember when a bad CD in
my SCSI CDRom drive would take out the entire system.

        Have you installed all the security patches for that? (Sorry
gang - I know he wasn't asking about security, but I gotta ask just out
of habit... That's my job...)

        If this is as old as that kernel and what your distro would indicate,
you've got a lot of trouble.

        This could be trouble depending on how it's configured.

        From that distro, you could be broken into.

        You're having a hardware problem that's screwing up the kernel.
If it's a tape drive, don't use that drive until you get that kernel
upgraded to handle the error more gracefully. If it's not a tape drive,
best of luck, I think you are about to loose a hard drive.

        You've also got several packages on that system with known security
holes and have just broadcast that fact onto the net. I would advise
upgrading that distribution. Sorry about being the bringer of bad news
but I'm sure you would rather here it that way than be asking out to get
rid of an intruder on your system.
