This is a crash with Cassandra 0.7.0-beta3 but I am pr= etty sure I also have got this on a rc1 server too ( We are dropping and recreat= ing keyspaces when this happens)

I do have the JNA enabled but it looks like it is stil= l calling an external program – presumably this would cause it to ask for the s= ame memory as the parent process and hence die?
