Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of the IBM Communications Server   *
    *                 for z/OS Version 1 Release(s) 13 IP:         *
    *                 Enterprise Extender (EE)                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: 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.

    + for common networking tips and fixes.  The URL for these    +
    + homepages can be found in Informational APAR II11334.       +
    +-------------------------------------------------------------+
    

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.
