  ****************************************************************
  The TRUNCATE failure may occur if the statement is executed
  while another DB2 agent is holding a partition-level drain on
  the table space.  The TRUNCATE statement, which requests a
  space-level drain, fails immediately rather than waiting for
  the other agent's drain to be released.
  
  The V11 DSNB5ULK abend may occur during an unusual situation
  where a castout operation has been split across two I/Os, and
  pages were found to be locked for castout by another member.
  In this case, an unlock failure is supposed to be tolerated,
  but the "tolerate unlock failure" flag gets reset between
  the I/Os.
  

Problem conclusion

• The space-level drain logic has been modified to avoid an
  unnecessary immediate failure when another agent holds a
  partition-level drain.
  
  The V11 castout logic has been modified to no longer reset the
  "tolerate unlock failure" flag between I/Os.
