Service stops immediately

Hi
after forcing the agent service to start it stops immediately with the following message :

INFO   | jvm 1    | 2013/09/10 08:41:02 |
INFO   | jvm 1    | 2013/09/10 08:41:12 | Could not create connection; - nested throwable: (org.postgresql.util.PSQLException: The connection attempt failed.); - nested throwable: (org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.postgresql.util.PSQLException: The connection attempt failed.))
