DYNUPGRDFAIL, Unable to dynamically upgrade block 0xaaa in database yyy due to lack of free space in block
DBCERTIFY/Run Time Error: There was not enough free space in the block to convert it in place to the current format during normal database access. This indicates that the DBCERTIFY database certification procedure was not properly carried out.
Action: Either mark the block free (making appropriate index changes) or downgrade the database and re-run DBCERTIFY (both phases).
