Red Hat system not booting up

Hello,

I had a linux server running mysql db without any issues, it just panic'd and now its not coming up , unfortunately we do not have backup for this server as well can anybody help on this. Following is the error

Memory for crash kernel (0x0 to 0x0 ) notwithin permissible range
Red Hat nash version 5.1.19.6 starting 
setuproot: moving /dev/ failed: No such file or directory 
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys : No such file or directory
ERROR opening /dev/console: No such file or directory
Trying to use fd 0 instead.
WARNING: can't access (null)
exec of init ((null)) failed!!!: Bad Address 
Kernel panic - not syncing: Attempted to kill init!

Thanks in advance.

Have you tried booting with another kernel (if applicable)? Is this a virtual server?

Try adding crashkernel=500M* " in your GRUB file or upon reboot as a parameter to the kernel. This doesn't seem to be related to the next errors though.

*Play a bit with this number to find the best value, or set it to "auto".

This is the most critical problem I see here.

Could you give a little more info about "not booting"

It's just a little hard for me to follow. So you turn it on, it has power - how far through boot does it go. Have you tried/are you able to get in to single user mode?
