I've seen Oracle crash on a VMWare Linux environment because it's processes are killed by OOM -- the OutOfMemory Killer -- which happens when VMWare's "memory balloon" architecture blows up a balloon and "steals" memory from the server. "sar -r" showed 2GB mysteriously disappearing from a 4GB server.
