Error description
The EJBConfigData holds a reference to the DD objects. EJBContainer has dropped its reference to this object, but the security object still holds a reference. EJBContainer cannot clear the references in the EJBConfigData, as security actually uses them, and EJBContainer cannot determine when security is done.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server who run Enterprice Java Beans (EJB) * **************************************************************** * PROBLEM DESCRIPTION: Memory usage can be improved when * * running EJBs when application security * * is enabled. * **************************************************************** * RECOMMENDATION: * **************************************************************** Security code keeps reference to EJB data. As the EJB specification evolves, the size of EJB data that is necessary to support the specification is increased. As a result, increased memory area is taken up by security code if a large number of EJBs are running on the system.
Problem conclusion
Following top-level security custom property has been introduced with this apar. Custom property: com.ibm.websphere.security.release.ejb.reference Value: true (release ejb data that is not related to security) Default is false. When the value is set to true, security code will only keep reference to security-related EJB data for better memory usage. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.5.
