Do you build your own kernel?  If so you can turn this timing down to 250Hz 
or something and see if that affects things.  You could also try the 'nohz=on'
boot parameter if you don't want to build your own kernel and that will turn on
dynamic ticks, overriding the 1000Hz option (I think - haven't tried it myself).

If you want to get the best from your system you really should compile your
own custom kernel and then you have complete control of your system and are
free to use whatever kernel version you like (i.e. not tied to those published
by your distro).

Your servers shutdown randomly and you don't know why?  Where is the love?
