APAR status

  • Closed as program error.

Error description

  • If IIDR CDC for z/OS is shutting down, and an Agent connection
    is concurrently terminating, it is possible to mis-reference the
    storage used to support the Agent's communication.  This will
    cause a program check, which is trapped.  However, the recovery
    logic is unable to associate the error with the Agent
    connection, so a diagnostic dump is produced.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of IIDR CDC for z/OS who have Agent    *
    *                 sessions that are frequently started and     *
    *                 ended.                                       *
    ****************************************************************
    * PROBLEM DESCRIPTION: If an Agent session is abandoned by the *
    *                      client concurrently with the IIDR CDC   *
    *                      for z/OS address space being shut down, *
    *                      there is a possibility that an improper *
    *                      storage reference will occur, causing   *
    *                      an ABEND S0C4.  While this ABEND is     *
    *                      trapped and recovered, the error cannot *
    *                      be associated with the abandoned Agent  *
    *                      session, so a system dump is requested. *
    ****************************************************************
    * RECOMMENDATION: APPLY CORRECTIVE SERVICE                     *
    ****************************************************************
    
    Occasionally, a system dump may be requested if an Agent session
    has been abandoned concurrently with the address space ending.
    

Problem conclusion

  • Logic to associate the abandoned Agent connection with the
    storage resources has been corrected.
