Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server 6.1 and 7.0 using the                *
    *                  Administrative Console.                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: Slow memory leak while using the        *
    *                      console on large topology environments. *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    There are classes in the administrative console
    which are holding onto workspace, session and other objects
    using ThreadLocals even after a console logout. Thus, creating
    a memory leak. This leak is noticeable only on very large
    environments.
