I doubt this is a driver upgrade issue but am not sure. can someone throw more light on this? This is quite a critical issue and needs to be fixed immediately.
I tried running ksymoops but no luck...
please guide...

What Linux distribution?

Just before this started had there been any changes to the system in the way of software installations, package upgrades, or changes in hardware?

Have you checked to see if all of the system cooling fans, including CPU coolers are operating properly?
If you use standard kernel then It looks like hardware problem.
Try to ask for your hardware master for help.
Hi


       Have you tried tuning up kernal for os hardening ? Have u edited /etc/sysctl.conf also tried to edit /proc file system ?

       If not this seems to have procfs error

this seems to be memory segmentation related ...

HI,

i am using Linux RH 7.3 with krnel : 2.4.18-3
i have not recomplied or rebuild the kernel. Since this is running on HP Proliant server , i am trying to install its support pack which will update all the drivers including BIOS.

Also i am goin to  stop pcmcia, autofs and smbfs daemons  after checking if they are not being used by my application.
