Thank you guys.
I installed jna using yum and then put jna.jar on the classpath and
everything seems fine.

Hi everybody,
I'm running cassandra 0.7.5 on about 20 RHEL 5 (24 GB RAM) machines and I'm
having issues with snapshots, json sstable conversions, and various nodetool
commands due to memory errors and the lack of the native access C libraries.

Ouch, that redesign is a bit nasty. jna.jar in this folder is the same as the one I last got 3.2.7http://java.net/projects/jna/sources/svn/show/trunk/jnalib/dist?rev=1182AaronOn 15 Feb, 2011,at 09:48 AM, mcasandra wrote:

Memory locking is permitted for non-root on modern Linux, but is
subject to resource limitations (ulimit -l). I believe this also
applies to mlockall() (and not just mlock()), provided that you lock

In order to continue on memory optimizations, I've been trying to

version of cassandra.

Hi,
In order to continue on memory optimizations, I've been trying to use the
JNA. However, when I copy the jna.jar to the lib directory? I get the
warning. I'm currently running the 0.6.5 version of cassandra.
