  ****************************************************************
  When the structure castout owner member of a group buffer
  pool (GBP) does GBP checkpoint, if a pageset's castout
  owner member is not the structure castout owner and is
  unavailable to do castout, a special castout process starts.
  This process may physically open the pageset. If the open
  fails, the special castout process may not clean up claims
  held during the open. Following drainers can fail since the
  claimers never go away.
  

Problem conclusion

• The special castout logic has been modified to do cleanup when
  the physical open fails.
  

Temporary fix
