In my experience that's the hallmark of runaway resource consumption
under Linux. Is anything useful going into the logs before they lock up
completely? Are you in a position to track incoming connections to the
box? Or even just to run top on it and see what's taking resources when
it freezes?

Definitely sounds like resource exhaustion (memory/swap or process
