  ****************************************************************
  Log input records can cause all available memory in
  the subordinate address space to be allocated.
  Additional buffers or other necessary control blocks
  then cannot obtain memory.  Different modules may be
  in control when the request for additional storage
  is made, and the failure symptoms can vary.
  

Problem conclusion

• AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
   GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  The buffer pool manager now reserves 1M of storage
  to be used for DRF control blocks and for system
  termination processing.
  Log input buffers will be spilled to dataspace
  storage when additional buffers are needed and not
  available.
  
  FRXBPG0$: reserves 1M safety cushion that cannot
  be used for buffer pool storage
  FRXPSDR0, FRXWSPL0, FRXLSRT2, FRXLSE15, FRXLSE35:
  cooperatively manage the queue of Log input buffers
  and the external dataspace storage to increase the
  available buffer pool capacity.
