To me based on the stack trace, it looks like the connection pool is trying
to cleanup connections. The initial class started with: PoolMaintenance.
Typically connections are pooled and left open for users to reuse, at a
configurable time, connections are typically closed and reopened.
I would recommend looking at your connection pool cleanup settings and try
turning them off temporarily. You can also get the Java source from JT400
and see how this stack trace is being kicked off and controlled.
Thanks, Paul holm
