It has worked very well over 6 months (almost near one year), however, at few days ago it happened that entire system freeze.

$ uname -r

$ cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant)
I guess that my system hasn't any update.
The following are logs before system freeze.

Re: host freeze with RH AS4, Error: kernel BUG at kernel/exit.c:840!
I had a RedHat AS4 host that is running Oracle 9.2.0.7.
It has worked very well over 6 months (almost near one year), however, at few days ago it happened that entire system freeze.
The related logs within /var/log/messages are

[oracle@dbserv12 product]$ cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 2)
Thanks, I understand that we need to update the Kernal, but want to make sure the Root cause of this Server's freezing...

Re: host freeze with RH AS4, Error: kernel BUG at kernel/exit.c:840!
https://bugzilla.redhat.com/show_bug.cgi?id=150653
Finally, we patched the kernel level to 2.6.9-42.ELsmp (RHAS 4.4) to solve this issue.
Also, at the moment we have asked RedHat Support through hot-line '0080-186-1036' for that, we got the same answer from them.
Hope above is helpful to you.
