Description of problem:
This morning I couldn't log into my server (ssh), open xterm-windows and samba
didn't work. The machine replied to ping, but nothing else.
I was forced to boot. After that I looked into /var/log/messages
(timestamp information removed):

As I look into other messages file, I can see that this did happen
once before, May 16. The time, messages and process are exactly the same.

There is a cron job in cron.daily which caused this to happen:
[root@pullasorsa cron.daily]# cat rpm
rpm -qa --qf '%{name}-%{version}-%{release}.%{arch}.rpm\n' 2>&1 \
        | sort > /var/log/rpmpkgs

The rpm package version is:
[root@pullasorsa cron.daily]# rpm -q rpm

Version-Release number of selected component (if applicable):

How reproducible:
Couldn't Reproduce

Additional info:

I had some crashes before this bug (reported as bug # 90990) so I run memtest86
for about 48 hours (all test and only standard set of tests) and it couldn't
find anything. I'm not sure if this is related to it.

Atleast these crashes seem to happen when there are lot of disk activity (see
bug 90990: backup script, samba, rpm, updatedb). I did shutdown the machine with
-F to force fsck on reboot. It didn't find anything wrong with hard drives.

vmscan.c:118 kernel panic with 2.4.20-20.9 + bootup info

The very same bug did hit my friends server last night. This is what he got. It
seems that there's something fishy going on with reclaim_page() ... that's my
guess, anyway.

My friends server has Red Hat 9.0 with latest kernel errata installed. The same
system used to work without a hitch even under heavier load, but couple of days
after he installed the new kernel this oops did hit. And during the last few
days he even didn't stress the server.
Comment 2 Janne Pikkarainen 2003-11-04 04:13:12 EST
Oh dear. I just heard that my friends server is quite a bit
overclocked.  The box used to run Windows and overclock settings were
tuned for it ("Does this thing still boot? Good, let's O/C a bit more!
Does it still boot? No... let's go down a step."), but since Linux
actually uses the hardware :-), overclocking made the box very crashy. 

He will restore it to default settings and see if that helps to this
problem. Personally I think that calming down the server will resolve
this case for him.
Comment 3 Bugzilla owner 2004-09-30 11:41:01 EDT
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
