    * PROBLEM DESCRIPTION:                                         *
    * (sysroute of PM92758)                                        *
    *                                                              *
    * With Enterprise Extender, the stack is                       *
    * leaking ECSA storage when sending EE                         *
    * test probes or null XID responses over                       *
    * an IUTSAMEH link.                                            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * For EE test probes and null XID responses                    *
    * over IUTSAMEH, EZBIFOUT is not marking                       *
    * the send as being over IUTSAMEH which                        *
    * prevents EZBIFIUT from properly freeing                      *
    * the storage associated with the outbound                     *
    * send.                                                        *
    ****************************************************************
    

Problem conclusion

  • Change EZBIFOUT to properly mark EE test probes
    and null XID responses over IUTSAMEH as being
    associated with IUTSAMEH to that the stack
    properly frees the storage associated with
    the send.
