Error description

  • When you use inbound web service with policy set settings. For
    every inbound request there will be a policy set workspace
    created and stored in memory without being released after use.
    This made the memory keeps on increasing and leading to
    java.lang.OutOfMemoryError.
    
       The heapdump shows these objects in abundance.

    An policy set workspace is needed for loading the policy set
    settings. When an inbound request message  reached inbound web
    service we will create a policyset workspace to load policy
    set data configured for this inbound web service. The
    workspace will not be released automatically when the request
    is complete. We need to add code to delete that after use. The
    same happens when you use web service integration to issue an
    request to the target web service server with police set
    settled.
    

Problem conclusion

  • A fix is available for IBM Business Process Manager V8.5.0.1
    to release the policy set workspace after use.
