[jboss-user] [JCA/JBoss] - "Connection is not associated with a managed connection", Ca

[spotlight2001]

I moved a legacy app (jboss328SP1 hibernate 2x) to a jboss501ga.

datasource type:
<local-tx-datasource>

In my tests no errors. In production (only with a lot of users) I encountered:


  | Connection is not associated with a managed connection.org.jboss.resource.adapter.jdbc.jdk6.WrappedConnectionJDK6 at 7cb375d0
  | 

interpretation: over jdbc connection, a jboss connection is wrapped
but the wrapper is empty. the original jdbc connection inside is no longer there. (according to the jboss5 source)


in the log I found more information above:


  | Closing a connection for you.  Please close them yourself
  | 

interpretation: 
org.jboss.resource.connectionmanager.CachedConnectionInterceptor
this class is charged with closing connections which it thinks are no longer needed.


So what can I do? In my test-environment I am unable to reproduce these errors.

Q1) How can I reproduce such an error in my test environment.

Q2) Will these params help (postgres) against "Connection is not associated with a managed connection"?
<new-connection-sql>select 1</new-connection-sql>
<check-valid-connection-sql>select 1</check-valid-connection-sql>
<min-pool-size>5</min-pool-size>
<max-pool-size>20</max-pool-size>
<idle-timeout-minutes>10</idle-timeout-minutes>


Any ideas where to search for an answer?

I used google.
