The DBUTLTY RETIX function will produce a snap dump if there are duplicate values in the table for keys defined as UNIQUE or a Master Key defined as allowing no duplicates. It dumps the key id followed by the key value.
In the above example the duplicate key is for key id x'18' (24 decimal)
The duplicate value follows the keyid: 7288005607AF72880056F7F7F4F8
Snap dumps for duplicates will also be produced by the LOAD and MASADD functions.
You need to remove the duplicate rows from the table.
