Resolution

Clear out the LevelDB corruption applying the following steps:

1. Stop all nolio services on NAC_SERVER.
2. Remove the directory LevelDB from ..\nes:  <RA_HOME>\activemq-data\nes\LevelDB
3. Remove the directory LevelDB from ..\nac:  <RA_HOME>\activemq-data\nac\LevelDB
4. After removal of this directory, start nolio services normally, and the folders will be rebuilt on startup.
