Yes there is a way, but what you are asking is probably a bad idea. Why do you need reboots? Linux is not like windows, it doesn't require reboot unless you make a manuel kernel upgrade. Even if things go ugly, you can fix them in other ways.

What you are desicribing should be solved otherwise, if everything is lagging, that's probably due to some disk input/output queue, possibly due to swap, and needs a ram increase. What is your server configuration? How much ram are you using?

2 giga ram

Is this what you have, or what you are using?

A quick and simple way to get a general idea of what is happening is open an ssh session and just leave top running. If the server crashes you can see what is happening and at least start the troubleshooting process. It might be something very easy and obvious.

open an ssh window as root (or really and user) and simply run top Then when it crashes you can look at what is left on the screen. When you say 35-40% is that of memory, buffers/cache, or swap? It makes a big difference

Open SSH and type this: free -m It will give you three or four lines of result, paste them here when your server is lagging.
