    During shutdown, the supervisor (CSQXSUPR) may free up storage
    used for extended trigger messages. After freeing the storage, a
    pointer may still reference the extended trigger message area
    and cause an abend S0C4-11 to occur.
    

Problem conclusion

  • Processing has been amended to ensure the invalid pointer
    reference is correctly updated.
