Hi,

Recently my production application was inaccessible which is deployed in JBoss7.1.1 even though everything was normal at server level.

I have forced to restart my services and once restarted everything back to normal. While analyzing i found the below errors in logs:

ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (pool-10-thread-151) Connection is not associated with a managed connection.org.jboss.jca.adapters.jdbc.jdk6.WrappedConnectionJDK6@226d3a89

Could any one please explain what is this and is this cause of application inaccessibility?

Thanks,
