Hi,

WHM is informing me that i have 1 zombie process running.

A zombie is a piece of information left over by a process or thread that got detached from the process that created it. It doesn't hurt your server or take up resources, except for a small entry in the OS's process table. The entry simply contains the exit status of the process. A reboot fixes it, although somewhere I've seen utilities to clean these out.

Thanks for that.

If I reboot my server will everything (CPanel/WHM etc.) come backup automatically?

Yes, everything should come up okay after a reboot. But I wouldn't boot the machine because of one zombie.

Okay, i will leave it then for now.

On the subject of rebooting, is there any need or reason to rebooted every couple of weeks or not? Is it just a case of reboot when it is actually needed or does frequent rebooting help keep things inline?

Generally, there's usually not much reason to. One exception that comes to mind is if you're running a lot of Java servlets, it's helpful to reboot every now and then.
