SubjectOOPS 1.99.7
Hi. The following oops happened to our internet server (pentium 100,
a.out, GCC 2.6.3, 2 scsi disks). While running sniffit:

--8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<--

Ksymoops gives:

After the first message, almost any command gave a similar OOPS (ls,
tcpd, mgetty, agetty, bash, inetd, sshd) and I could not see files on
any directory. Shutdown was useless & I had to push the big
button... At reboot, two of our three partition needed extended fsck
care.

I include here the second oops message, they all end into the same
code.

If the other oopses can be of any help, I will be glad to mail
them. The system is up and running again, but I haven't restarted
sniffit...


Ciao
Carlo
