Hello,

Looks like you have a kernel with a bug known to RedHat. I've found some more sites indicating you should upgrade to the latest kernel for RHEL4, which solves this bug.

Kind regards,

Eric

thanks but i check in the site you gave,and there is no bug for this error.

When does the error occur? While you are running a specific application/program or any random time ?

No, I do not run any application or specific program!!
