Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 *
    *                 Release 0 Modification 1.                    *
    ****************************************************************
    * PROBLEM DESCRIPTION: Abend S878 occurs when using            *
    *                      CSQWDPRD/CSQWD701 to format queue       *
    *                      manager dumps.                          *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When formatting certain trace entries, the MQ dump formatter
    calls CSQWCNAM to get the name of the routine which wrote the
    trace entry. An error in CSQWCNAM resulted in the working
    storage obtained by this routine not being correctly freed,
    eventually exhausting the storage available to IPCS and
    resulting in the S878 abend.
    

Problem conclusion

Temporary fix

Comments

  • CSQWFMTC is changed to correctly free the working storage
    obtained when CSQWCNAM is called by the dump formatter.
