Shutdown Problem
Dear Experts
I have installed red hat 9.0 in my server (With RAID), yesterday when I restart the server with the command init 6 it shows the following error message.
Zkmem (1.1)
idt=0xc036f00
sct[]=0xc030a070
Can't fine kmalloc()!
and the server did not reboot or shut down at all. Can anybody help?

give us the output from your boot console (ctr-alt F10)
do you have actual or beta version of redhat?

Hi,
Is your RH9 connect to internet? If yes, then it could be compromised by some type of network attack.
Please
1. Pull out the network cable.
2. As root
touch /forcefsck
then power cycle to boot into single user mode.
3. Check all the log files for clues. (/var/log/messages.....).
4. Backup all the important data and configuration file. If you see something suspecious, then rebuild the system.
You can rebuid it on another disk and study the original disk.

no I don't think so there is some network attack , I think the problem may occurr due to red hat automatically update my system, can u suggest me how do I fix the problem without rebuild or resinstall redhat again.
> due to red hat automatically update my system
RedHat is not officially supported since May 1 2004. So it will not automatically update your system (by up2date)
unless you installed "yum" or "apt".
Please try the step 1 to 3 of my previous post first before we come to the conclusion.

I am using dynamic ip for ISP, there is no suspicious entry in my /var/log/messages
Did you run "fsck" to check your disk?
DDOS (Distributed Denial Of Service) attack will attack whatever the victim is regardless of the IP address.
Anyway, you can download the latest security patches to harden your RH9.
