  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.
