    * RECOMMENDATION:                                              *
    ****************************************************************
    In Websphere Liberty versions 20.0.0.7 through 20.0.0.11 there
    is a problem with communications between the JVM supplied Health
    Center function and the Liberty healthAnalzyer feature.  This
    problem prevents the healthAnalyzer feature from gathering heap
    statistics.  These statistics are vital to its ability to
    trigger the memory leak and memory usage conditions.
    

Problem conclusion

  • The healthAnalzyer feature has been modified to use the health
    center's updated interface.  The health center feature is only
    available at this time on IBM originated JVMs.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 20.0.0.12.  Please refer to the Recommended Updates page
    for delivery information:

Temporary fix

  • There is no work around for this issue other than avoiding the
    use of the affected fix packs.
