this doesn't look like an OOM to me.  If the kernel OOM kills Cassandra then 
Cassandra instantly vaporizes, and there will be nothing in the Cassandra logs 
(you will find information about the OOM in the system logs though, eg in 
dmesg).  In the log snippet above you see an orderly shutdown, this is 
completely different to the instant OOM kill.

Ciao, Duncan.
