Hello,

This noted as a bug you see in this post and the fixes are available in new update...

As Redhat says just use yum upgrade to update a kernel

See the Redhat pages and liunxcompitable site to check it

How to over come it?

As xasir said, you need to update your kernel to the latest version to overcome it. I'm sure an explanation of the bug is on the redhat pages like xasir mentioned as well.

Actually my server machine does't have an internet connection.

I know installing kernel in 32bit in following manner,
1)Download the sorce tar file from kernel.org
2) put it in /usr/src/ directory, and untar the file.
3)Use make menuconfig,make,make modules,make modules_install,make install.

So Can u please tell me the updating process of kernel in 64bit server edition.


Thanks in advance.
