Hi all:

 

Our application uses Jboss-hibernate with Postgres as the backend.

 

I’m seeing intermittently – the DB connections getting stale – and not getting returned to the Hibernate session pool. Some of the connections are as old as 9 days.

 

The pg_stat shows the connection as IDLE in the DB.

Is there anyway to correlate the Process id – the query that is used – or map it to the threads in the Java thread dumps? Need some lead to debug these IDLE connections.

 

Any help in this regard is highly appreciated.

 

Regards
