  a /DBR command is issued against the same database. The module
  DFSDYA00 reference DFSMDA member for the database recall
  request, but the DFSMDA member is released when the /DBR
  command is processed. DFSDYA00 tries to reference the DFSMDA
  member after it was released by the /DBR command and receives
  the 0C4 ABEND.
