[WBEL-users] High loads of CPU all of a sudden

[Alon]

Hi All,

I'm runnig WB3.0 Respin 3 on a DELL 1850 PE machine.
I have a single website that was running fine till few days ago.
I'm getting high CPU loads randomly and I can't figure out what is the cause.
I didn't detect any attacks from outside of the server, so this is of course confusing.

I decided to look into the File system as a possible problem area.
I tried to run fsck and got the following:


/ # fsck
fsck 1.32 (09-Nov-2002)
e2fsck 1.32 (09-Nov-2002)
/dev/sda2 is mounted.  

WARNING!!!  Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Do you really want to continue (y/n)? yes

Group descriptors look bad... trying backup blocks...
fsck.ext3: Invalid argument while checking ext3 journal for /

/ # 
----------------------------------------------------------------------------------------------------------------------
After running this and getting the error above,. I can't go anywhere:
See the following lines that came right after I ran the fsck:



/ # mount
-bash: mount: command not found

/ # su -
su: error while loading shared libraries: libpam.so.0: cannot open shared object file: No such file or directory

/ # whoami
-bash: whoami: command not found

/ # uptime
-bash: /usr/bin/uptime: No such file or directory

/ # cd

/root # whoami
-bash: whoami: command not found

----------------------------------------------------------------------------------------------------------------------


Now that can't be good.

Any suggestions? pointers? 
I have a live production server running,.. but I'm scared if something will happen to it.
I can format a new server and transfer all the data over, but do I need do this?

Any thoughts about this will be appreciated.

Thanks,

-Alon.
