JBossManagedConnectionPool - newbie

[newbie-jboss]

Hi all...

I'm running JBoss 3.2 with PostgreSQL and as a newbie I don't understand why jboss throws exception after letting my application stopped for a while....

JBoss is trying to remove a connection that hasn't been
used for a while. But the connection to the db has
already been broken.
