reload kernal without reboot

Hello!

Does anyone know howto reload your kernal without rebooting the machine?
I�ve updated the "/etc/security/limits.conf " file and need to make this active without rebooting the machine. this is Red Hat Advanced Server 2.1AS

limits.conf is applied during login, not reboot afaik. So restarting the services rather than the whole computer ought to work.

You can't reload the kernel without rebooting the machine. In the newest kernel (2.6.13) they added a new feature called kexec which will reload a kernel without physically rebooting the machine, but it still kills all of the services and downs everything. At best, it is a faster way to reboot.

Reloading kernel is one of few things you can not do in Linux without reboot, but you could compile ee-everything as modules and reload them.
