Hi Erich,
I just checked mine and you are correct that DB is using the wrong Engine. It should be InnoDB.
Thanks for the heads up.

> Nifty. But that's a dangerous bug somewhere in the neutron Icehouse RDO code. We are using MySQL 5.1, which comes as the default for CentOS 6.5/RedHat 6.5, and the default engine is MyISAM for 5.1. Changing the default engine to InnoDB in my.cnf would have likely mitigated this.
