Cassandra will use JNA to try to mlockall for all pages currently mapped to
the process address space. On very small systems (1024mb
I figured out the issue. I'm using a VM and the template I had did not
configure enough virtual memory. I'm not sure what the minimum is but 2048
seems to work. For the record, I'm using
/usr/share/cassandra/lib/jna-4.1.0.jar
Thanks for all of the tips!

CentOS6 and every major version of C* from 1.1 through 2.1, but I would be
curious if there's maybe a memory leak or something fixed between 3.2.4 and

hardlinks for snapshots, both of which work.

Hello,
I always install JNA into the lib directory of java itself
Since I normally have java in /opt/java I put the JNA into /opt/java/lib.

it says
"Cassandra requires JNA 3.2.7 or later. Some Yum repositories may provide
earlier versions"
and at the bottom
"If you can't install using Yum or it provides a version of the JNA
We've been using jna-3.2.4-2.el6.x86_64 with the Sun/Oracle JDK for
probably 2-years now, and it works just fine. Where are you seeing 3.2.7
required at? I searched the pages you link and that string isn't even in
there.
Regardless, I assure you the newest jna that ships in the EL6 repo works

Hello,
I'm having problems getting cassandra to start with the configuration
listed above.
Yum wants to install 3.2.4-2.el6 of the JNA along with several other
packages including java-1.7.0-openjdk
The documentation states that a JNA version earlier that 3.2.7 should not
be used, so the jar file
