    You can use 'yum' to upgrade your OS. If you have note done this before i strongly recommand you to have your system admin or hire a system admin to do this job coz if anything goes wrong will corrupt your entire server..

    What is the main benefits of 3.5? It seems more important than 3.3->3.4 ?

    It's far from a cPanel bug, it's a flaw in RHEL 3.5 which Redhat do not want to fix. The easiest way to prevent the damage is to add caching-nameserver to your skip list, otherwise remove the rpm, ( make a backup of named.conf ), and copy the renamed or backedup named.conf to the origonal location. Restart named and your done.

    I know that rack911.com offer this service for ~ $50.

    How critical is this upgrade? I know it should probably be done, but I am curious if time is little on our side to investigate and hire a proper admin to do the installation. The rack911 possibility sounds good above and perhaps I'll check that out.

    Thank you!

    If you need to hire an admin to run a command "yum update" and reboot your machine into a new kernel, I would definitly recommend the services of Steven @ Rack911.com.

    No updating means you are leaving potentially vulnerable services and programs installed on your machine which can be exploited or used to dos your server. This is really something you should be taking care of on a daily basis. I would also advise you aquire a local test box to trial such things on before doing so on a production box, unless the box means nothing to you, and is just a play toy.
