SubjectFull-featured Oops w/2.0.0
Hi. 2.0.0 here with recently hand-installed ELF cc & libs, and all
latest libraries & utils. Pentium 100 w/16MB. It is our internet
gateway.

In the early hours of Saturday (nobody was here) the following two oopses
were recorded (text + ksymoops translation):

(note the lack of the "Code: " line. It just was not there in the
syslog output). The two happened in the same second (07:20:57). Then,
at 07:40:03 crontab started updatedb: I got:

At 07:44:28 I got the firsty of a long series of oopses from nmbd
(samba daemon) that got restarted regularly because of requests from
other machines in the net:

(always at the same place). Similar stuff came from inetd at
07:55:46. Also from mgetty and httpd. Last message I got from gated at
14:23:38, always pointing to the same place, then probably syslogd
also went down. I connected from home on another box on the net, and I
found that I could not do ssh, telnet, rsh, or other stuff. But ping
was working OK, and the machine was GOING ON DOING ITS NETWORK ROUTING
BUSINESS!! So we went on receiving mail for all the time (the mail
server is on another machine) and I could talk to the internet as
normal!!

Anyway, when I got to the office today I tried to login & got an oop
that's similar to the ones above. So I had to use the Big Switch. When
rebooting I had to run fsck on my main disk by hand, because duplicate
inodes were found. E2fsck fixed everything and the box is now up and
running again :-)

If you need more info, please ask. It is the first time that I see
such stuff. I had to reboot the machine several times last week,
because of power downs. But it had been up since June, 27.

If you need more info, please ask.

Carlo
