I have been going through the mailing list and compiling suggestions to address the swapping due to mmap issue.

1) Use JNA (done but)
Are these steps also required:
- Start Cassandra with CAP_IPC_LOCK (or as "root"). (not done)

And what is CAP_IPC_LOCK?

I saw that suggestion in
https://issues.apache.org/jira/browse/CASSANDRA-1214.

I do not yet know how to run cassandra or a java process with that privilege, still researching and hoping my sysadmin knows better.
