Well, the first thing to find out is whether CherryPy dies
on its own (this 
can happen for instance if if tries to print something to
the console but 
there is no console) or whether it's being killed by
something else ... (for 
instance, Apache can kill its children after a while).

One thing you can do is to try and run your CP server in the
console and see 
if the problem happens...
