  ****************************************************************
  A shared IMS bridge queue was altered to use an undefined
  storage class (and so cease to be an IMS bridge queue), and to
  be get(enabled). Both of these changes resulted in the IMS
  bridge being notified of the changes, and as the queue was
  no longer an IMS bridge queue, the IMS bridge task for the queue
  was stopped.
  Both notifications attempted to delete the associated QTE
  control block, leading to the second abending while following
  a pointer just cleared by the first.
  

Problem conclusion

• An error in the serialisation of QTE deletion was corrected.
