As you say not much to go on. Obviously something is causing Nagios to die.
I've just had a quick look at the change list for later releases > 2.4 and
there are some bug fixes for seg faults which presumably could cause Nagios
to die silently. It may be worth updating to the latest and greatest version
to see if this solves your issue. If this isn't possible, then I guess an
inspection of the Nagios log file to see what it was doing last before it
died is in order.
