Workaround solution for Leap second on Redhat 5.3/4.0 without upgrade Linux kernel

Latest response

Hi guys

Is there any workaround solution for Leap second on Redhat 5.3/4.0 without upgrade Linux kernel?
Now we still have some old server working on field, and didn't want to upgrade the Linux kernel for leap second.
Since it is risks if upgrade Linux kernel fail.

I find an article in link https://access.redhat.com/articles/199563
To stop NTP and switch to slew mode during leap second.
Does it work?
If not, any workaround?

Thanks

Michael,

A kernel is not updated, a new kernel is installed beside the current kernel.
So if the "update" fails you can fallback to the current kernel.

Running RHEL 4.0 is unsupported anymore, so if things go wrong you may get an issue with Red Hat support.

Kind regards,

For REHL 5.3, could we switch NTP to slew mode and bypass the leap second?
