He says he disabled JNA.  You can't mmap without JNA can you?

I'm experiencing a steady growth in resident size of JVM running
Cassandra 1.0.7. I disabled JNA and off-heap row cache, tested with
and without mlockall disabling paging, and upgraded to JRE 1.6.0_31 to
prevent this bug [1] to leak memory. Still JVM's resident set size
grows steadily. A process with Xmx=2048M has grown to 6GB resident
size and one with Xmx=8192M to 16GB in a few hours and increasing. Has
anyone experienced this? Any idea how to deal with this issue?
