Depends. If it's due to a kernel crash there might be some stack trace info in the /var/log/messages, if it's anything else you'll need monitoring tools (Dstat, Atsar, Atop) running *before the crash*.

Well, you could look at all your application logs and generally audit the box. Maybe there's even core dumps.
