As it "just goes down", the first idea that comes to mind is to increase
the log level (assuming you haven't done that already). With more verbose
logging you might find what you're looking for.

Also, it might be of interest whether the server goes down at a relatively
silent time (not much user traffic), or at some peak traffig time. Also,
as the crashes occur at night time, have you considered this could be
related to some automated maintenance during the night (f.ex. backups)?
