I want to know about kernel update frequency(because they are causing server reboot) for different operating systems such as Linux(CentOS, Debian, Ubuntu Server Edition), FreeBSD NetBSD, OpenBSD.

Could anyone help? I'm not trying to make a Linux vs BSD question as it is against forum rules.
First of all, I quite agree with the cluster idea.
If it is really of the question, put whatever distro you want and simple DON'T update kernel. You are not forced to apply each update of the distro. Actually in a production machine, you don't update at all, at least not automatically. If for example the "automatic" update request new version of apache, your machine will have a small down time. If problems with the new configuration files arise, then it will be big down time.

Don't update anything.

NAME

       update-initramfs.conf - configuration file for update-initramfs

DESCRIPTION

       The configuration file allows one to disable the update action from update-initramfs.

GENERAL VARIABLES

	update_initramfs
	      Default  is  yes	for  running  the  latest  initramfs-tools  hooks  in the newest Linux image.  Setting it to all updates any known
	      initramfs.  It is possible to set it to no for remote servers or boxes where conservative manners needs to be applied. This disables
	      the update_initramfs -u call.

	backup_initramfs
	      If set update_initramfs keeps an .bak file of the previous initramfs. If unset the backup initramfs will not be kept.

FILES

       /etc/initramfs-tools/update-initramfs.conf

AUTHOR

       The initramfs-tools are written by Maximilian Attems <maks@debian.org>, Jeff Bailey <jbailey@raspberryginger.com> and numerous others.
