Error description

• After applying APARs PI51564/PI58662 (PTFs UI36527/UI36528) and
  activating the new function by specifying MFSPFV=Y in the DFSDC
  proclib member, an ABENDU0732 occurred with message DFS0637W
  HIOP REQUEST NOT SATISFIED DUE TO POOL EXPANSION LIMIT. With the
  new function active, HIOP buffers are being obtained, but never
  released if the 3270/SLU2 terminals experience an abnormal
  disconnect resulting in the NSEXIT driven by VTAM.

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  Part DFSCVCF0 has been modified to release the MFS protect
  work buffer during abnormal session termination. This change
  will prevent the accumulation of orphaned MFS Protect work
  buffers in HIOP.
