----------------------------------------------------------------

I was testing the debian installer for DataStax Community 1.2.6 and noticed first that when
we install that we do a startup/shutdown, but also that on a debian platform (not centos,
rhel, mac or ubuntu) that I consistently see this exception during that initial shutdown.
Not sure if this is relevant or not but I was testing on squeeze (debian 6.0.1) using this
EC2 AMI: ami-75287b30.
