Agent Log

Description of problem:
In the agent.log there are continuous Exceptions as "Database has been closed "  and its not able to query the database where as when connected through H2 console, i am able to query the results successfully.I suppose the connection of H2 DB was lost.
When i restarted the rhq-agent there were no exceptions.It was normal.


Following is the stack trace:

Even if this is not affecting any functionality it should be fixed because it compromise the troubleshooting analysis becase all the logs are filled up with this exceptions and important messages can be lost.
Beside that the logs files keeps increasing unnecessarily.
