    ****************************************************************
    When workspace are not cleaned up they accumulate and use up
    memory.  If enough workspaces accumulate it will cause the
    server to experience an OutOfMemoryError.
    Workspace accumulation is typically the result of Java admin
    clients not disposing of workspaces correctly.
    

Problem conclusion

  • This APAR provides a serviceability improvement to log the
    excessive growth of workspaces that may be used to avoid an
    OutOfMemoryError.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.14/9.0.0.9.  Please refer to the Recommended
