    * PROBLEM DESCRIPTION:                                         *
    * Storage leak may occur when an SSL/TLS channel fails to      *
    * start. May eventually lead to chinit abending S878 RC10.     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When an SSL/TLS channel fails to complete its connection, a
    small amount of associated storage containing distinguished
    names for certificates may not be released. When these failures
    are frequently occurring (e.g. due to channel retry), then
    eventually the storage leak may lead to an S878 RC10 abend in
    the channel initiator address space.
    

Problem conclusion

  • Processing has been amended to ensure that associated storage is
    released when an SSL/TLS channel fails to connect.
