FUSE ESB

Pooled Sessions are not being returned during the deployment of services.

 Description  « Hide
There are some services that when you try to hot deploy them they generate a ClassNotFoundException for the referencing bean in the xbean.xml file for that service.

Those same services will be deployed successfully when the system is restarted but this issue only happens when they are hot deployed.

The process of deploying these services causes the pooled sessions to be borrow but they are not being released.

The problem is that the pooled sessions are not being returned causing these sessions to be exhausted. Then the call to borrow another session caused the system to hang because the borrowObject call will cause the thread to wait until a session has been returned. Which never happens.

Here is the stack trace that shows the issue:

The problem is this issue will exhaust all 500 pooled objects.
